Toppings are what separate bubble tea from any other cold drink. The chewy texture, the burst of fruit juice, the visual appeal of layered ingredients — toppings are 50% of the bubble tea experience. But for UK cafe owners building a menu, the topping landscape can be confusing. This guide breaks down the five main bubble tea topping families, when to use each, and how to choose the right mix for your menu.
Topping Family 1: Tapioca Pearls (Classic Boba)
What they are: Chewy starch balls made from cassava root. The original bubble tea topping invented in Taiwan in the 1980s, and still the iconic ingredient that gives bubble tea its name (the "bubbles" or 珍珠 — pearls).
Texture: Soft, chewy, slightly resistant — like a gummy bear that melts in your mouth.
How they're served: Boiled in water for 25-30 minutes, then soaked in brown sugar syrup. Used within 4 hours of cooking — they harden after that.
Best paired with: Milk tea (classic), brown sugar boba, taro milk tea, matcha latte.
Two sizes available:
- 9.5mm pearls — standard bubble tea size. Use with 12mm straws. Best for classic milk teas.
- 7.5mm pearls — smaller pearls. Use with 10mm straws or no straw. Best for milkshake-style cups and dessert drinks.
Vegan / Halal: Yes — made from plant-based cassava. Gluten-free: Yes.

Topping Family 2: Popping Boba (Juice-Filled Spheres)
What they are: Spheres filled with real fruit juice. The outer membrane is made from seaweed extract (sodium alginate), which bursts when bitten releasing the juice.
Texture: Firm outer shell, liquid centre — pops/bursts on bite.
How they're served: No cooking required. Spoon straight from the tub into the drink. Add 30g per 500ml drink. Once opened, refrigerate and use within 5 days.
Best paired with: Fruit teas (matching flavour or contrast), iced teas, slushies, frozen yoghurt toppings.
17 UK flavours available:
- Fruit popping boba: mango, strawberry, lychee, passion fruit, peach, blueberry, kiwi, raspberry, cherry, watermelon, pineapple, pomegranate, cantaloupe, lime, orange, green apple
- Dessert popping boba: chocolate, coffee
Vegan / Halal: Yes — seaweed-based membrane, no gelatin. Gluten-free: Yes. Shelf life: 18 months sealed.

Topping Family 3: Coconut Jelly (Nata de Coco)
What it is: Chewy cubes of nata de coco — fermented coconut water made into a translucent, jelly-like texture. Originally from the Philippines, now a staple bubble tea topping.
Texture: Firmer than tapioca, with a slight crunch followed by a gentle chew. Holds shape well in iced drinks.
How it's served: Drained from syrup, spooned into drinks. No cooking required.
Best paired with: Fruit teas (especially matching flavours), iced teas, frozen yoghurt, dessert frappes.
9 UK flavours available:
Vegan / Halal: Yes. Gluten-free: Yes.

Topping Family 4: Han Tien Jelly Balls (Konjac Jelly)
What it is: Small jelly balls made from konjac (a Japanese root vegetable). Sweet, soft texture, distinct from coconut jelly. Often eaten alone as a snack in East Asia.
Texture: Soft, slightly bouncy, melts when bitten. Less chewy than tapioca, less firm than coco jelly.
How it's served: Spooned straight from bag. No cooking.
Best paired with: Brown sugar boba drinks (tiger sugar), milk tea, dessert bases.
3 UK flavours available:
Vegan / Halal: Yes. Gluten-free: Yes.
Topping Family 5: Lychee Jelly (Fruit Jelly)
What it is: Flavoured jelly cubes with real fruit juice content. Sits between coco jelly (firmer) and Han Tien jelly (softer) in texture.
Texture: Firm cube with gentle bite, gradually releases fruit flavour.
Best paired with: Lychee fruit tea (matching), rose tea, dessert drinks.
Available: Lychee Jelly 3.85kg

Frequently Asked Questions
What's the difference between popping boba and tapioca pearls?
Tapioca pearls are chewy starch balls that need cooking. Popping boba are juice-filled spheres that burst on bite and require no cooking. Pearls go in milk teas; popping boba goes in fruit teas.
Are all bubble tea toppings vegan?
The 5 families covered here (tapioca, popping boba, coco jelly, Han Tien, lychee jelly) are all vegan and halal. Some specialty toppings like pudding and grass jelly may contain dairy or non-vegan ingredients — always check the product page.
How long do cooked tapioca pearls last?
4-6 hours at room temperature in brown sugar syrup. After that, texture hardens and pearls become inedible. Cook in small batches throughout service.
Can I mix multiple toppings in one drink?
Yes — many UK shops offer "double topping" options (e.g., pearls + popping boba) at +£0.80-£1.20. Particularly popular in dessert-style drinks.
Why are some popping boba 14% real juice and others lower?
Boba Tea Company's premium line (mango, strawberry) contains 14-14.5% real fruit juice for natural flavour. Standard line uses concentrated essence. Both vegan and halal — the difference is flavour authenticity.
What's the best topping for a brown sugar milk tea?
9.5mm tapioca pearls (classic), warm. Soak in brown sugar syrup before adding. Optionally add brown sugar Han Tien jelly for double texture.
