In a saucepan, bring the water to a boil.

Gradually add the Ai Yu Jelly powder while stirring continuously to avoid lumps.

Once the powder is completely dissolved, add the sugar and continue stirring until it is fully dissolved as well.

Remove the mixture from the heat and let it cool to room temperature, stirring occasionally to prevent a skin from forming on the surface.

Transfer the mixture to a container and refrigerate for at least 4 hours, or until set.

Once the jelly has set, cut it into cubes and serve chilled with ice cubes for a refreshing treat.
