In a saucepan, bring the water to a boil. Remove the pot from the heat and add the agar powder and sugar. Stir until fully combined.
In a silicone mold, arrange your preferred choice of fruits. Red dragon fruit can lend a stunning pinkish-red hue, while a mix of green grapes and blueberries presents an appealing contrast against the translucent jelly.
Carefully pour the gelatin mixture into the mold.
Place the mold in the refrigerator for 2-3 hours or until fully set. Once set, they are ready to be served.
