01 - Wash, peel, and dice strawberries, kiwi, mango, and pineapple into small, bite-sized pieces. Rinse blueberries and set all prepared fruit aside.
02 - Combine water and agar agar powder in a medium saucepan. Whisk thoroughly to disperse powder evenly and prevent clumping.
03 - Bring mixture to a boil over medium heat, stirring constantly. Reduce heat and simmer for 2 minutes until agar agar is completely dissolved and liquid becomes clear.
04 - Add sugar to the hot liquid, stirring continuously until fully dissolved. Remove from heat source.
05 - Pour in fruit juice and mix well. Let cool for 2-3 minutes until slightly warm but still fluid (do not allow to begin setting).
06 - Distribute prepared fruit pieces evenly across the bottom of a silicone mold or glass dish, ensuring uniform presentation.
07 - Gently pour warm agar agar mixture over arranged fruits, ensuring all pieces are submerged. Allow to cool at room temperature, then refrigerate for at least 45 minutes until completely set.
08 - Unmold carefully or cut into cubes. Serve chilled for best texture and flavor.
