Wash and pat the molds dry. Set aside (see Note 1).
Prepare the fruits.
Wash and hull the strawberries. Cut them into small pieces.
Peel the mango. Slice and cut into cubes.
Peel the kiwi fruits. Chop the fruits into small pieces.
Wash the blueberries.
Peel the dragon fruit. Slice and cut into cubes.
Measure water into a small saucepan.
In a separate bowl, measure the sugar and agar agar powder. Mix with a spoon to combine (see Note 2).
Pour the sugar and agar agar powder mixture into the saucepan of water. Stir to disperse the sugar.
Turn on the heat to medium low and cook the jelly. Stir constantly for the first minute to avoid the jelly from clumping. Thereafter, stir occasionally.
Continue to cook the jelly until it reaches a rolling boil (see Note 3). Turn off the heat. Let the solution cool down slightly before pouring into the cups (see Note 4).
In the meantime, layer the fruits into the jelly cups.
Start with the dragon fruits. Divide them between each jelly cup, making sure they are evenly distributed. Use the back of a spoon to press them down lightly to form an even layer.
Top the dragon fruit with blueberries, followed by kiwi, mangoes and finally strawberries (see Note 5).
Spoon the jelly solution into the cups (see Notes 6 & 7).
Tap the cups lightly on the kitchen countertop to release any air bubbles trapped between the fruit pieces.
Break any visible bubbles on the surface of the jelly with a toothpick. Top up the cups with more jelly if required.
Place the fruit jelly cups in the refrigerator for about 1 to 2 hours to set completely before serving.
