Bring 1000ml of water to a boil in a medium-sized pot. Add 60g of tapioca pearls and simmer for 15–18 minutes, stirring to prevent sticking.

Turn off the heat and cover the pot, allowing the pearls to steep for 10–15 minutes.

Drain the pearls, transfer them to a bowl with ice water, and let soak for 3 minutes before draining again.

Cut 100g of watermelon into 1cm cubes. Blend 300g of watermelon with 400ml of coconut milk until smooth.

Layer 50g of watermelon cubes and 2 tablespoons of drained tapioca pearls in clear glasses. Pour in the watermelon-coconut smoothie until the glasses are 90% full.

Serve immediately for the best texture.
