01 - Wash, peel, and dice all fruits into small, bite-sized pieces. Set aside in a bowl.
02 - Combine water and agar agar powder in a medium saucepan. Whisk thoroughly to dissolve the powder completely.
03 - Bring the mixture to a boil over medium heat, stirring constantly. Reduce heat and simmer for 2 minutes until the agar agar is fully dissolved.
04 - Stir in the sugar and mix until completely dissolved. Remove from heat, then add the fruit juice and mix well. Let cool for 2-3 minutes, but do not allow it to set.
05 - Distribute the diced fruits evenly in a silicone mold or glass dish, ensuring they are spread in a single layer.
06 - Gently pour the agar agar mixture over the fruits, ensuring all pieces are covered. Let cool to room temperature, then refrigerate for at least 45 minutes until fully set.
07 - Unmold the jelly or cut into cubes. Serve chilled for best flavor and texture.
