Step 1: Prepare the Agar-Agar
In a small bowl, mix the agar-agar powder with a little bit of water (just enough to dissolve the powder). This helps prevent lumps from forming when you add it to the hot liquid.
Step 2: Heat the Coconut Water and Milk
Pour the coconut water and coconut milk into a saucepan. Add the sugar if you’re using it. Warm the mixture over medium heat, but don’t let it boil. Stir continuously until the sugar has fully dissolved.
Step 3: Add the Agar-Agar
Once the sugar has dissolved, add the dissolved agar-agar to the saucepan. Keep the mixture on medium heat and stir constantly for about 2-3 minutes. Agar-agar needs to be heated to activate its gelling properties, but the mixture should not boil.
Step 4: Pour into Molds
After the agar-agar is completely dissolved in the mixture, remove the saucepan from the heat. Carefully pour the liquid into molds or a shallow dish. Silicone molds work great for individual servings, but you can also use a square dish and then cut the jelly into pieces once it's set.
Step 5: Let It Set
Allow the mixture to cool down to room temperature. Then, refrigerate it for at least 2 hours, or until the jelly is firm and fully set. The setting time can vary based on the thickness of the jelly and the temperature of your refrigerator.
Step 6: Garnish and Serve
Once the coconut jelly has set, you can unmold it by gently pulling the edges away from the mold and inverting it onto a serving plate. If you used a dish, cut the jelly into your desired shapes.
Garnish with fresh fruits such as mango, berries, or kiwi for added flavor and a beautiful presentation.
