US Skittles use corn syrup and 9 synthetic dyes. UK Skittles use glucose syrup and plant-derived E-code colorants. Purple flavor differs — grape (US) vs. blackcurrant (UK). UK Skittles are vegan; US are not. Titanium dioxide removed from US formula in 2025.
You'd think Skittles taste the same worldwide. They don't. US and UK versions are two different products — different ingredients, different color systems, and different flavors. This guide covers every real difference with verified 2026 data, so you know exactly what you're getting in each bag.
Whether you're a candy enthusiast curious about regional formulas, a vegan checking ingredient labels, or someone who spotted the phrase "are Skittles banned in the UK" and wants the real answer — this breakdown covers all of it, ingredient by ingredient, flavor by flavor.
What Are the Real Differences Between US and UK Skittles?
US Skittles are formulated with corn syrup and a synthetic-dye color system. UK Skittles use glucose syrup and plant-derived E-code colorants. Both contain the same five core colors, but the purple piece uses entirely different fruit flavoring: grape in the US, blackcurrant in the UK.
This isn't a minor tweak. The two formulas reflect fundamentally different regulatory environments — the US Food and Drug Administration (FDA) permits synthetic color additives that are more tightly restricted under EU and UK food law. Mars, the manufacturer of Skittles candy, has adapted the product for each market rather than selling a single global formula.
Here's a data-verified comparison of the key differences at a glance:
| Feature | 🇺🇸 US Skittles Original | 🇬🇧 UK Skittles Fruits |
|---|---|---|
| Base Sweetener | Corn syrup | Glucose syrup |
| Fat Type | Hydrogenated palm kernel oil | Palm fat |
| Color System | Synthetic dyes (named additives) | E-code colorants (plant-derived) |
| Number of Color Additives | 9 listed | 8 listed |
| Purple Flavor | Grape | Blackcurrant |
| Green Flavor | Lime (historically) / Green Apple | Lime |
| Glazing Agent | Confectioner's glaze (lac resin) | Carnauba wax |
| Titanium Dioxide | Removed in 2025 | Already absent |
| Vegan Status | Not confirmed (glaze is animal-derived) | Core range: Vegan ✓ |
| Calories (US serving) | 110 kcal per serving, 21g added sugar | 397 kcal per 100g, 73.7g sugar |
How Do US and UK Skittles Ingredients Compare?
The most striking difference is not the packaging, but the formula: US Skittles rely on a corn-syrup and synthetic-dye system, while UK Skittles use glucose syrup and plant-style colorants. The fat source also differs — hydrogenated palm kernel oil (US) versus palm fat (UK).
Reading both ingredient panels side by side tells you almost everything about why these two Skittles taste and look different. Let's break it down by ingredient category.
Base Sweetener: Corn Syrup vs. Glucose Syrup
US Skittles list corn syrup as the second ingredient after sugar. UK Skittles list glucose syrup in the same position. These are functionally similar — both are liquid sweeteners derived from starch — but corn syrup is made from corn (maize), while glucose syrup in the UK is typically derived from wheat or potato starch.
The practical difference for taste is subtle. Corn syrup has a slightly flatter sweetness profile, while glucose syrup can contribute a marginally softer, less sharp sweetness. It's not something most people consciously detect, but it contributes to the overall flavor impression when combined with other ingredient differences.
Fat Source: Hydrogenated vs. Non-Hydrogenated
US Skittles use hydrogenated palm kernel oil — a partially processed fat that contributes to the hard shell structure of the candy. UK Skittles use palm fat, a less processed alternative. The hydrogenation process in the US version is what gives Skittles their slightly firmer outer shell texture, which some tasters notice as a slightly "snappier" bite compared to the UK version.
Color Additives: Synthetic Dyes vs. E-Code Colorants
This is where the two formulas diverge most significantly on paper. The US Skittles ingredient panel lists 9 color additives by name:
US Skittles Color Additives: Red 40 Lake, Yellow 5 Lake, Blue 2 Lake, Yellow 6 Lake, Blue 1 Lake, Yellow 6, Red 40, Yellow 5, Blue 1.
These are petroleum-derived synthetic dyes approved by the FDA. They produce vivid, consistent colors and are among the most commonly used food colorants in the United States. However, they require warning labels in the EU and are tightly restricted in the UK market.
UK Skittles Fruits use 8 E-code colorants, most of which are plant or mineral derived:
UK Skittles Color Codes: E162 (beetroot red), E163 (anthocyanins — from plants), E170 (calcium carbonate — mineral), E160a (beta-carotene — from plants), E100 (curcumin — from turmeric), E132 (indigotine — synthetic, but used in far lower quantities), E133 (brilliant blue FCF), plus carnauba wax as a glazing agent.
While not all UK E-codes are natural in the strictest sense, the overall color system in the UK product leans significantly more toward plant-derived sources than the US version. This is a direct result of EU food color regulations that have been maintained in UK law post-Brexit.
Glazing Agent: Lac Resin vs. Carnauba Wax
The shiny outer coating on Skittles comes from different sources in each version. US Skittles use confectioner's glaze, which is made from lac resin — a secretion produced by the lac insect. This makes US Skittles technically non-vegan. UK Skittles use carnauba wax, derived from the leaves of a Brazilian palm tree. This is a plant-based glazing agent, and is one of the reasons the core UK range can be marketed as using a vegan recipe.
What Flavors Does Each Version of Skittles Have?
Both US and UK Skittles come in five fruit flavors per standard pack. Four of the five flavors are identical or very similar. The purple piece is the biggest difference: grape in the US, blackcurrant in the UK. The green flavor has also historically differed between markets.
Skittles candy gets its regional identity from flavor localization — the practice of adapting products to match local fruit preferences and taste expectations. Blackcurrant is a beloved British flavor with deep cultural roots in the UK, where it's the base of drinks like Ribena and widely used in sweets. Grape, on the other hand, is one of the most dominant candy flavors in the American market and has no equivalent prominence in British confectionery.
| Color | 🇺🇸 US Flavor | 🇬🇧 UK Flavor | Notes |
|---|---|---|---|
| 🔴 Red | Strawberry | Strawberry | Identical in both markets |
| 🟠 Orange | Orange | Orange | Very similar; minor sweetness variation |
| 🟡 Yellow | Lemon | Lemon | Similar; US slightly more candy-forward |
| 🟢 Green | Lime (historically) / Green Apple | Lime | US has had multiple versions of the green flavor over time; UK maintains lime |
| 🟣 Purple | Grape | Blackcurrant | Most distinctive regional difference |
📌 Confirmed data: "Purple Skittles alone reveal the regional split: grape in the United States, blackcurrant in the United Kingdom." — Tasting Table, flavor comparison review.
The green Skittles debate is worth a separate note. In the US, the green Skittles flavor has shifted back and forth between lime and green apple over the years — the Skittles brand has explicitly referenced "lime vs. green apple" as a flavor topic on its own US platform. The UK product has consistently maintained lime as the green flavor. For lime fans, the UK version has been the more reliable choice over the past decade.
Beyond the Original / Fruits comparison, both markets have developed significantly different limited-edition and extension flavors. The US Skittles lineup includes varieties like Tropical, Wild Berry, Sour, and Sweet Heat. The UK market has developed its own regional variants. And in Asian markets, Skittles have gone even further with flavors like Yogurt, Flower, Fruit Tea, and Berry Mix — fruit-forward, creamy, or floral profiles that don't exist in either the US or UK standard lineup.
Why Do US and UK Skittles Use Different Color Systems?
The US uses FDA-approved synthetic petroleum-derived dyes. The UK follows EU-derived food law that restricts synthetic colorants and requires warning labels for certain dyes. Mars reformulated the UK product to use plant-derived and mineral E-code colorants to comply — and to appeal to label-conscious British consumers.
The regulatory divide between the US and UK food systems is visible on no label more clearly than a bag of Skittles. This isn't about one system being safer than the other in a legal sense — both are approved within their respective frameworks — but it does reflect different regulatory philosophies about synthetic food additives.
Why the EU and UK Restrict Synthetic Dyes
The European Food Safety Authority (EFSA) has taken a precautionary approach to food colorants that goes further than the FDA. In particular, the EFSA raised concerns about a group of six synthetic dyes — including Sunset Yellow (Yellow 6) and Tartrazine (Yellow 5) — that appear in the US Skittles formula. Products in the UK that contain these additives are required to carry the warning: "May have an adverse effect on activity and attention in children."
Rather than apply this label to Skittles — which are primarily marketed to a candy-buying audience that includes children — Mars chose to reformulate the UK product with a different color system. This is a common industry response to European food labeling requirements.
What the Color Difference Looks Like in Practice
On a visual level, side-by-side comparison of US and UK Skittles can reveal subtle differences in color vibrancy. The synthetic dyes in the US version produce very saturated, consistent colors that many candy consumers associate with the "classic" Skittles look. The E-code colorants in the UK version can appear slightly less vivid in some pieces — particularly the purple, which using anthocyanin-based E163 instead of a synthetic red-blue combination. Most people don't notice this difference under normal conditions, but in a direct comparison it can be visible.
The Titanium Dioxide Timeline
Titanium dioxide (E171) was used in US Skittles as a whitening agent — it contributed to the candy's bright, opaque interior coloring and the white sugar coating. This additive became a significant controversy:
- 2022: The European Food Safety Authority ruled that titanium dioxide could no longer be considered safe as a food additive. The EU formally banned it in food products. The UK followed with compatible restrictions.
- Pre-2025: The UK Skittles formula had already removed titanium dioxide as part of the broader EU-compliant reformulation.
- 2025: According to a 2025 BBC report, Mars confirmed it had removed titanium dioxide from its US Skittles portfolio at the end of the previous year — a significant reformulation driven by years of consumer pressure in the American market.
This makes the titanium dioxide removal a clear example of regulatory changes shaping product formulas across markets. The US product took longer to change not because it was legally required to, but because consumer advocacy and negative press created market-level pressure that eventually exceeded the cost of reformulation.
How Many Calories Are in US Skittles vs UK Skittles?
US Skittles contain 110 calories per serving with 21g of added sugars. UK Skittles show 397 kcal per 100g with 73.7g of sugars. These figures use different serving formats and are not directly comparable without normalizing by weight.
Both versions of Skittles are sugar-dense candy — that's the starting point. But comparing calorie counts between US and UK packaging requires care, because the two markets use different labeling conventions.
| Metric | 🇺🇸 US Skittles (per serving) | 🇬🇧 UK Skittles (per 100g) |
|---|---|---|
| Calories | 110 kcal | 397 kcal |
| Carbohydrates | 26g | ~90g |
| Total Sugars | 21g added sugars | 73.7g |
| Fat | ~1g | ~4.5g |
| Serving Reference | Listed per serving (approx. 40g) | Listed per 100g (standard EU/UK format) |
Source: US Nutrition — Skittles.com official US nutrition panel; UK Nutrition — UK product nutrition reference.
The US nutrition panel lists calories per serving (approximately 40g), while UK nutritional data follows the EU/UK convention of showing values per 100g. When you normalize the US figure to a per-100g basis, US Skittles come out to roughly 275 kcal per 100g, which is notably lower than the UK figure of 397 kcal per 100g.
This difference is likely attributable to the different fat sources and their relative energy densities, as well as possible formula differences in total sugar content. It's not a dramatic health distinction — both are candy — but it is a measurable difference between the two formulas, not just a labeling artifact.
Are Skittles Banned in the UK? The Real Answer
No — Skittles are not banned in the UK. They are sold in every major UK supermarket. The confusion stems from the fact that the US formula contains ingredients restricted under EU/UK food law. The UK sells a separately formulated version that complies with those regulations.
This is probably the most Googled question about Skittles outside of the US — and the answer is unambiguous. UK Skittles are freely available in Tesco, Sainsbury's, ASDA, and every corner shop that stocks candy. There is no ban, no import restriction on the UK-formula product, and no regulatory action pending against Skittles candy in Great Britain or Northern Ireland.
So where does this question come from? A few sources have contributed to the confusion:
The Titanium Dioxide Misconception
When the EU banned titanium dioxide in food products in 2022, several consumer publications ran headlines suggesting that products containing E171 were effectively "banned" in Europe. Some of those articles mentioned Skittles specifically, as the brand had disclosed titanium dioxide as an ingredient in the US version. Readers — particularly in the US — misread this as a product ban rather than an ingredient restriction that had already led to a UK-specific reformulation years prior.
The Synthetic Dye Warning Label Issue
US Skittles contain synthetic dyes that require warning labels under UK food law. In theory, a UK retailer could sell US-formula Skittles if they added the required allergen and additive warning text. In practice, Mars doesn't import the US formula into the UK at all — the UK gets its own product. So there's no "ban" in legal terms, just a different product for a different regulatory market.
The California Skittles Story
In 2023, California briefly passed legislation targeting titanium dioxide and three other additives in food products. This was widely covered as a "Skittles ban" by US media. The law was later amended to remove titanium dioxide from its scope. This US-based story may have further seeded the "Skittles banned" narrative that people then search globally.
The bottom line: UK Skittles are legal, widely available, and use a formula specifically developed for the UK market. The question of whether they're "banned" is a misreading of ingredient-level regulatory differences between markets.
Are UK Skittles Vegan? What About US Skittles?
The core UK Skittles Fruits range is described by the brand as using a vegan recipe — a significant consumer-angle distinction. US Skittles use confectioner's glaze derived from lac resin (an insect product), which makes them not suitable for vegans or vegetarians who avoid insect-derived ingredients.
Vegan status is one of the clearest practical differences between the two formulas, and it matters to a growing segment of candy buyers in both markets.
UK Skittles: Vegan Confirmed for Core Range
The UK Skittles Fruits range has been reformulated to remove animal-derived ingredients. The key changes that enabled the vegan claim were:
- Replacing confectioner's glaze (lac resin, insect-derived) with carnauba wax (plant-derived from Brazilian palm)
- Removing gelatin, which had historically appeared in some Skittles formulas
- Using E-code colorants that do not require animal testing under current EU regulations
According to Vegan Checkr's product analysis, the core UK Skittles range meets vegan criteria. The brand's own UK FAQ describes the core range as using a vegan recipe. The Squishy Cloudz variant is specifically excluded from this vegan claim — buyers interested in vegan candy should check individual product packaging.
US Skittles: Not Vegan
US Skittles retain confectioner's glaze in the ingredient panel. This glaze is made from shellac — a resinous secretion of the lac insect (Kerria lacca). While some vegans do not consider insect products in the same category as animal products from mammals or birds, the mainstream vegan position is that shellac makes the product non-vegan.
US Skittles also do not carry any vegan certification or brand-level vegan claim. For vegan consumers in the US seeking a Skittles-style candy experience, sourcing the UK-formula product or exploring the Asian-market Skittles range (which uses different glazing conventions) is worth considering.
What Changed in US Skittles in 2025?
Mars removed titanium dioxide from its US Skittles portfolio in 2025, following years of consumer pressure and the precedent set by the EU's 2022 ban. This was a major reformulation — one that brought the US ingredient panel closer to the UK formula for the first time in the brand's history.
The 2025 titanium dioxide removal marks the most significant reformulation of US Skittles in at least a decade. Understanding why it happened — and what it means — requires a brief look at the regulatory timeline.
Why Titanium Dioxide Was Controversial
Titanium dioxide (TiO₂) is a white pigment used in hundreds of food products to add opacity, brightness, and a consistent white-base color. In candy like Skittles, it contributed to the intense, saturated appearance of the candy coating. It's also used in sunscreen, paint, and toothpaste.
The food-safety controversy around TiO₂ centers on nanoparticle form: when titanium dioxide is milled to nanoscale, it behaves differently than standard-sized particles and raises questions about absorption in the gut. In 2021 and 2022, the EFSA reviewed the available evidence and concluded it could no longer confirm TiO₂ was safe at current intake levels — a precautionary ruling that led to the EU ban effective August 2022.
The Regulatory Timeline
| Year | Event |
|---|---|
| 2021 | EFSA publishes findings raising concerns about titanium dioxide (E171) genotoxicity |
| August 2022 | EU formally bans titanium dioxide in food products |
| 2022–2023 | UK food law maintained EU-compatible restrictions; UK Skittles already titanium dioxide–free |
| 2023 | California legislation briefly named titanium dioxide in food ban (later amended to remove it) |
| 2025 | Mars confirms removal of titanium dioxide from US Skittles at end of previous year |
📌 Cited data: "Mars said in 2025 that it had stopped using titanium dioxide in its US Skittles portfolio at the end of the previous year." — BBC, 2025 report on Skittles reformulation.
The removal of titanium dioxide brings the US ingredient panel closer to the UK formula, but the two products are still far from identical. The synthetic dye system remains in the US version, the fat source remains different, and the purple flavor remains grape versus blackcurrant. The titanium dioxide change is meaningful from a transparency and regulatory convergence standpoint — but the products are still two distinct formulas.
What Do US vs UK Skittles Actually Taste Like in a Side-by-Side Test?
US Skittles taste sweeter and more candy-forward overall. UK Skittles taste slightly tangier with more fruit character. The purple piece is the clearest single-piece proof of the difference: grape is round and sweet, blackcurrant is tarter, deeper, and more distinctly British in flavor.
Blind taste comparisons between US and UK Skittles consistently return the same finding: the differences are real, they're noticeable, and they're most obvious in the purple piece. Here's a flavor-by-flavor breakdown based on documented comparisons.
Red — Strawberry
Both versions deliver strawberry as the dominant flavor note. The US red Skittle tends to be slightly sweeter and more candy-strawberry in profile — the kind of strawberry you associate with American candy more broadly. The UK red Skittle has a marginally more tart finish, which some tasters find closer to fresh strawberry rather than strawberry candy.
Orange — Orange
Orange is where the two versions are most similar. Both deliver a citrus-sweet orange candy flavor. The US version is very slightly sweeter. Most tasters who do blind comparisons find orange the hardest pair to distinguish. It's genuinely close.
Yellow — Lemon
The US yellow Skittle sits in a sweeter, less tart lemon candy territory. The UK yellow has a brighter lemon note with more tartness — which UK lemon sweet products generally skew toward, consistent with UK confectionery preferences for acidic citrus candy.
Green — Lime vs. Lime (and the Green Apple Era)
In periods when the US green Skittle was lime, the two were nearly identical. When US Skittles switched to green apple, the green piece became one of the biggest differences between versions — green apple versus lime are entirely different flavor directions. As of the most recent US formula, the Skittles brand itself has referenced lime as a branded flavor topic — but the US green has had an inconsistent history that makes it the least reliable flavor for direct comparison.
Purple — Grape vs. Blackcurrant (The Definitive Difference)
This is the clearest, most immediate, most unmistakable flavor difference between US and UK Skittles. Grape is sweet, round, and familiar — the kind of artificial grape flavor you encounter in countless American candy products. Blackcurrant is tarter, deeper, more complex, and intensely fruity in a way that grape candy rarely achieves. If you've had Ribena, you know what blackcurrant tastes like. The UK purple Skittle leans into that direction.
For US candy fans trying UK Skittles for the first time, the purple piece is the one that most often prompts a strong reaction — either "this is fascinating" or "I miss the grape." For UK consumers trying US Skittles, the grape is often described as sweeter but simpler.
Overall Taste Profile Assessment
| Taste Attribute | 🇺🇸 US Skittles | 🇬🇧 UK Skittles |
|---|---|---|
| Overall Sweetness | Higher — corn syrup base | Slightly lower — glucose syrup base |
| Tartness | Lower across all colors | More tartness, especially lemon and purple |
| Fruitiness | Candy-fruit forward | More fruit-forward, less candy-sweet |
| Shell Texture | Slightly firmer (hydrogenated fat) | Marginally softer shell |
| Most Distinctive Piece | Purple (grape) | Purple (blackcurrant) |
| Best for… | Classic American candy sweetness | More complex fruit flavor, vegan-friendly |
How to Do Your Own US vs UK Skittles Taste Test at Home
Running a proper blind comparison takes about 15 minutes and requires no equipment beyond the candy itself, two bowls, and water to reset your palate between pairs. Here's the method.
Source Both Versions
You need authentic US Skittles and UK Skittles Fruits. US versions are available at import candy stores and online at newmunchies.com. UK versions are available from UK online retailers. Make sure you have the standard Original (US) and Fruits (UK) varieties — not a limited edition — for the most representative comparison.
Remove All Packaging
Place US Skittles in Bowl A and UK Skittles in Bowl B. Do not label which is which — or have a friend set it up so you genuinely don't know which is which. Brand awareness and expectation bias are real factors that affect taste perception.
Sort by Color and Pair Up
Pull matching colors from each bowl and line them up: red, orange, yellow, green, and purple. The purple pair is the one to focus on — it will show you the clearest flavor difference of all five colors.
Taste Each Color Pair Back to Back
Taste one piece from each pair. Chew slowly and note: How sweet is it? Is there any tartness? Does it taste like the actual fruit it's named after, or more like candy? Drink water and wait 30 seconds between each color pair to reset your palate fully.
Compare the Ingredient Panels Afterward
After the blind test, look at both ingredient lists side by side. Find the base sweetener (corn syrup vs. glucose syrup), the color additives (named dyes vs. E-codes), and the glazing agent (confectioner's glaze vs. carnauba wax). This is the "aha" moment where the ingredient differences map directly onto the taste differences you noticed.
Which Version of Skittles Should You Try?
If you want a sweeter, more classic candy profile and the standard grape purple — try US Skittles. If you want a slightly more fruit-forward profile, a vegan-friendly formula, and the blackcurrant experience — try UK Skittles. If you want to go further beyond either — try Asian-market Skittles flavors like Yogurt, Flower, or Fruit Tea.
There is no objectively better version. The right one depends on what you're looking for. US Skittles deliver the candy experience that most American consumers grew up with — bold, sweet, and consistent. UK Skittles offer a slightly more complex and fruit-forward candy with a vegan-friendly formula and cleaner label.
For candy explorers, the more interesting question is what lies beyond both standard formulas. Asian-market Skittles flavors — developed for Chinese, Japanese, and South Korean consumers — use entirely different flavor profiles: creamy yogurt, delicate floral, tea-infused, and sharply sour variants that exist nowhere in the US or UK standard lineup. These represent the third direction in Skittles candy innovation, and for many import candy fans, they're the most interesting of the three.

Frequently Asked Questions About US vs UK Skittles
Q1. What is the main difference between US and UK Skittles?
US Skittles use corn syrup and 9 synthetic dyes; UK Skittles use glucose syrup and plant-derived E-code colorants. Purple flavor also differs — grape (US) vs. blackcurrant (UK) — and the glazing agent: lac resin (US) vs. carnauba wax (UK).
Q2. Are Skittles banned in the UK?
No — Skittles are not banned in the UK. The UK simply sells a separately formulated version that complies with UK/EU food additive regulations. The "ban" misconception stems from confusion with ingredient-level restrictions, not a product ban.
Q3. Are UK Skittles vegan?
Yes — the core UK Skittles Fruits range is vegan, confirmed by the brand. It uses carnauba wax (plant-derived) instead of confectioner's glaze (shellac). US Skittles are not considered vegan. Note: Squishy Cloudz is excluded from the vegan claim.
Q4. What flavors are in UK Skittles?
UK Skittles Fruits: strawberry (red), lime (green), orange, lemon (yellow), and blackcurrant (purple). Blackcurrant is the key difference from the US version, which uses grape. The UK has consistently kept lime as the green flavor.
Q5. Why did Skittles change their formula in 2025?
Mars removed titanium dioxide from US Skittles in 2025, following the EU's 2022 ban and years of consumer pressure. The UK formula had already removed it earlier. This was the most significant convergence between the two formulas to date.
Q6. How many calories are in US vs UK Skittles?
US Skittles: ~275 kcal per 100g. UK Skittles: ~397 kcal per 100g. The difference is a real formula gap — not just a label format issue — making UK Skittles higher in energy density per gram.
Q7. Do US and UK Skittles taste different?
Yes — US Skittles taste sweeter and more candy-forward; UK Skittles are slightly tangier and more fruit-forward. The clearest difference is in the purple: grape (US) vs. blackcurrant (UK). Orange is the most similar pair across both versions.
Final Thoughts: Explore the Full World of Skittles
US and UK Skittles are a perfect case study in how a single candy brand can become two genuinely different products when shaped by regional regulations, local flavor preferences, and ingredient supply chains. The formula differences aren't cosmetic — they run from the base sweetener to the color system to the glazing agent to the purple flavor itself.
The story also reflects a broader shift in global candy formulation: increasing regulatory pressure on synthetic additives, growing consumer awareness of ingredient labels, and the removal of titanium dioxide from US Skittles in 2025 all point toward a slow convergence between the US and UK formulas. Whether they'll ever reach the same recipe is an open question — but the trend is toward fewer differences over time.
For candy explorers who want to go beyond the standard US or UK formula, the Asian-market Skittles lineup offers a third direction entirely. Yogurt, Flower, Fruit Tea, Berry Mix — these are flavors developed for markets where fruit candy profiles lean creamy, floral, or tea-infused rather than purely fruit-forward. They're a different expression of the Skittles candy format, and for many import candy fans, the most interesting one.
