Begin by placing the small pearl tapioca in a bowl and covering it with water. Let the pearls soak for about 30 minutes.
In a medium saucepan, combine the full-fat coconut milk, granulated sugar, and salt. Heat the mixture over medium heat, stirring occasionally until the sugar is fully dissolved.
Once the tapioca pearls have soaked, drain them and add them to the warm coconut milk mixture. Cook for about 15-20 minutes, stirring frequently.
After the tapioca is fully cooked, remove from heat and stir in the pure vanilla extract.
Let the Coconut Tapioca cool slightly before transferring it to serving bowls. Garnish with fresh diced mango and toasted coconut flakes if desired.
