Cooking Tapioca Pearls: The Perfect Step-by-Step Guide

Tapioca pearls (also called boba) are the heart of every bubble tea. Prepared properly they are soft, pleasantly chewy and perfectly sweet. In this guide we show you step by step how to cook tapioca pearls perfectly – and how to make them completely from scratch if you want to.

What are tapioca pearls?

Tapioca pearls are made from tapioca starch, which is obtained from the cassava root. They are naturally gluten-free and vegan. The classic black pearls also contain caramel or bamboo charcoal for their dark colour. They are also available in white (pure tapioca) or in colours. The starch itself is neutral in taste – the pearls only get their typical aroma from the sugar syrup.

What you need

• Tapioca pearls (50–80 g per serving)
• A large pot of water (at least 1 litre per 100 g of pearls)
• A sieve
• Brown sugar or sugar syrup for sweetening

Cooking tapioca pearls – step by step

1. Bring the water to the boil: use plenty of water – at least ten times the volume of the pearls. The pearls swell a lot and need room.
2. Stir in the pearls: add the tapioca pearls to the rapidly boiling water and stir immediately so they do not stick to the bottom of the pot.
3. Cook: as soon as the pearls float to the surface, put the lid on and cook for 2–3 minutes over medium heat. Always follow the instructions on the pack.
4. Let them steep: turn off the heat and let the pearls steep in the hot water, covered, for another 2–3 minutes – the longer, the softer.
5. Drain and rinse: drain through a sieve and rinse briefly with cold water. This stops the cooking process and washes off excess starch.
6. Soak in syrup: toss the pearls in sugar syrup or brown sugar straight away. This gives them their typical aroma and stops them sticking together or turning hard.

The doneness test: cut one pearl in half. If there is no white core left, they are ready.

Common mistakes – and how to avoid them

• Too little water: the pearls swell a lot and stick together. Always use plenty of water.
• Taking them out too early: better to cook them a little longer than too briefly – hard pearls with a white core are no pleasure.
• Letting them cool without syrup: the most common mistake. Without syrup the pearls turn rock hard.
• Putting them in the fridge: cooked pearls turn tough and hard in the fridge. It is best to use them within 4–6 hours.

Making tapioca pearls yourself – the basic two-ingredient recipe

Do you want to make the pearls completely from scratch? It works with just two ingredients – and it is especially good fun with children.

Ingredients: 100 g tapioca starch, 60–70 ml boiling water, optionally 1 tbsp cocoa powder or matcha for colour

1. Make the dough: put the tapioca starch into a bowl. Add the boiling water one tablespoon at a time and stir immediately.
2. Knead: knead the dough until it is smooth and mouldable – like modelling clay, not sticky.
3. Shape: roll small portions into thin ropes, cut off even pieces and shape them into little balls of about 1 cm.
4. Cook: cook for 15–20 minutes in boiling water until they are soft in the middle. Turn off the heat and let them stand for 15 minutes.
5. Rinse and sweeten: drain, rinse with cold water and put them straight into sugar syrup – that way they stay soft.

Make them yourself or buy them?

Making your own tapioca pearls is fun – but for a quick bubble tea at home, ready-made tapioca pearls are the more relaxed choice. They work more reliably and are ready to use within minutes.

Frequently asked questions

Why do my tapioca pearls turn out too hard?
The cooking time was too short or they were taken out of the pot too early. There must be no white core left inside. And: never let them cool down without syrup.

How long do cooked tapioca pearls keep?
Use cooked pearls within 4–6 hours. In syrup at room temperature they keep for a maximum of 8 hours – the fridge makes them hard.

Are tapioca pearls gluten-free?
Yes. Tapioca is obtained from the cassava root and is naturally gluten-free and vegan.
