Mix the agar agar powder with water (coconut layer ingredients) while stirring continuously. Let it rest for 15 minutes. During this time, the fruit layer will set.
1 tablespoon agar agar powder, 1 cup cold water
After 15 minutes, add coconut milk to a saucepan over low heat. Stir in the rested agar-water mixture, and ensure the agar dissolves fully. Add sugar, pandan, and salt, whisking or stirring until sugar is completely dissolved.
1 1/2 cup coconut milk, 1/4 cup white sugar, 1/2 teaspoon salt, 1 pandan leaf
Check if the fruit layer has set and become firm by gently touching it, then gently pour the hot coconut layer on top. Let the dessert set at room temperature for 20 minutes or until firm, and then place it in the refrigerator for several hours. Serve chilled and unmold right before serving.
