18 OZ watermelon or peach flavored Jell-O
12 OZ Lite Evaporated Skim Milk (95% fat free) no other milk will work
5 drops green food coloring
2½ C boiled water
1 C cold water
Vegetable oil or non-stick spray (to lubricate the mold)
Temperature:
Spray or smear oil into a dry mold wiping the excess away, and set the mold aside. Empty the packets of Jell-O into a large bowl. Add the boiling water and whisk until the powder is dissolved, approximately 3 minutes. Stir in the cold water. Pour in the skim milk and mix for 2 minutes. Add 5 drops of green food coloring to darken the mix and add that 'gray' color. Pour the mixture into the mold, but don't fill it to the top — leave approximately one inch. Refrigerate overnight.
* If a clear brain is desired, leave out the skim milk and add an additional 1½ cups of cold water.
