Soak Tapioca Pearls: Place tapioca pearls in a bowl and cover them with water. Let them soak for at least 30 minutes, or until they have plumped up and softened.
Boil Coconut Milk: In a saucepan, heat coconut milk over medium heat until it comes to a gentle simmer. Stir occasionally to prevent scorching.
Add Tapioca Pearls: Drain the soaked tapioca pearls and add them to the simmering coconut milk. Stir well to combine.
Cook Tapioca: Continue to cook the tapioca pearls in the coconut milk, stirring frequently, until they become translucent and soft. This usually takes about 15-20 minutes. Be patient, as tapioca pearls require time to cook properly.
Sweeten: Once the tapioca pearls are cooked, add sugar and a pinch of salt to the pudding. Stir until the sugar is completely dissolved and well incorporated into the pudding. Taste and adjust sweetness if necessary.
Cool: Remove the saucepan from the heat and let the pudding cool slightly. It will thicken further as it cools.
Chill: Transfer the coconut tapioca pudding to individual serving bowls or glasses. Cover and refrigerate for at least 2 hours, or until the pudding is thoroughly chilled and set.
