Make orange and green jellies as per the directions on the box. Dissolve the jelly powder in 1 cup boiling water and when completely dissolved add 1 cup of cold water.
Options:
For green can add cut green grapes orKiwi fruits
For orange can add orange wedges or strawberries
For white either use agar coconut cake with coconut flakes and almond flakes with lychee or Rambutan fruit pieces. Set them in refrigerator for few hours.
I used both agar in one and store bought rice pudding in some.
Better to set the jellies and then pile thenm together. First set green then out the agar or rice pudding in the middle then cut the orange jelly and place on top so the colors don’t mix.
