Place bottom-half mold over an icy cool water bath.
Keep the unused jelly liquid warm over the smallest heat setting on your range top (this to prevent it coagulate). Fill to about 3/4 of each half sphere.
Add flowers or decorative fruits. Use a toothpick to adjust shape/position or remove any bubble.
In case of using fruit for decoration, wait a couple seconds for the jelly layer to half-set before adding the fruit. This is so that it can hold the decoration in place.
Replace and secure the other top half sphere and fill the rest through the small hole on top. If using the smaller ice cube mold, then just fill to 3/4 of the mold, and snap the top layer on top.
Let sit to cool down to room temperature. Then chill in fridge until serving.
Serve cold after 30 minutes - an hour with soy powder and some syrup.
