How to make FLOWER ICE CUBES Buy ice trays for Big ice cubes (they will last longer), fill 1/4 way up and add edible flowers face down, freeze. Add more water to fill 1/2 way then freeze. Fill to top then freeze again. Use diststilled water that has been boiled and cooled. This gives the ice cubes this very clear (not cloudy) appearance! BEAUTIFUL for you and your guests!
