When Cantonese rice rolls meet tropical mango, something magical happens. You get this clever dessert from Qionghai, Hainan. Instead of rice milk, the wrapper is made with coconut milk – thin, smooth, and wrapped around big chunks of ripe mango. Served cold with a drizzle of mango sauce, it's a simple but delicious combination. It looks like a rice roll, but tastes like a refreshing tropical treat. No wonder it's become one of Hainan's most loved desserts.
