Iced Masala Chai with Brown Sugar Tapioca

By • Updated September 2026
Jump to Recipe ↓

This iced masala chai with homemade brown sugar tapioca pearls bridges the gap between traditional spiced tea and modern bubble tea. The whole spices are simmered gently, flash-chilled to preserve brightness, then poured over chewy pearls that taste like liquid brown sugar. It's the sort of drink that requires patience—and a digital cooking thermometer—to get the tapioca texture just right.

Tapioca pearls are notoriously fickle: too cool and they stay hard, too hot and they dissolve into mush. A reliable digital thermometer takes the guesswork out, letting you hold the cooking water at exactly 90–95°C for consistent, bouncy pearls. Once you've nailed the technique, you can batch-cook pearls and keep them in brown sugar syrup for quick assembly throughout the week—perfect for a UK summer treat that feels both nostalgic and new.

Instructions

1
Cook the pearls: Bring 1 litre of water to the boil in a medium saucepan. Add the tapioca pearls and stir gently. Use a digital cooking thermometer to monitor the water; reduce the heat to hold it at 90–95°C (do not let it drop below 85°C or boil hard). Cook for 20–25 minutes, stirring occasionally, until the pearls are translucent with just a pinpoint of white in the centre. They should feel chewy, not crunchy.
2
Make brown sugar syrup: While the pearls cook, combine 100 ml water and 2 tbsp brown sugar in a small pan. Simmer for 2 minutes until syrupy, then remove from the heat. Drain the cooked pearls in a sieve, rinse briefly under cold running water, then transfer to the syrup. Set aside to cool.
3
Brew the chai: In a clean saucepan, combine 500 ml water, the remaining 100 g brown sugar, cardamom, cinnamon, cloves and ginger. Bring to a simmer and cook gently for 5 minutes. Remove from the heat, add the tea bags (or loose leaf), cover and steep for 4 minutes. Strain into a jug and refrigerate until completely cold, or flash-chill by pouring over a bowl of ice.
4
Assemble: Divide the tapioca pearls and a spoonful of their syrup between two tall glasses. Fill each glass with ice cubes. Pour the chilled chai over the ice, leaving room at the top, then gently pour in the cold milk—it will swirl and marble. Serve immediately with a wide straw.

🫖 Equipment You'll Need

A digital cooking thermometer is essential for perfectly chewy tapioca pearls. Unlike stovetop guesswork, it lets you hold the cooking water at a steady 90–95°C—the sweet spot where starch gelatinises evenly without breaking down. That precision turns gummy disasters into bouncy, café-quality bubbles every time.

Expert Tip: Make-Ahead Pearls

Cooked tapioca pearls will keep in their brown sugar syrup, refrigerated, for up to 24 hours. Beyond that they start to harden. For best texture, cook fresh or reheat refrigerated pearls by dunking in boiling water for 30 seconds.
