Here is the rainbow jell-o salad that I made for Thanksgiving. I've had this recipe since my college days when we made it in a class. It is time consuming but easy to make. The results look cool and is really yummy!
-1 small package of each of the following jell-o flavors: Black Cherry, Raspberry, Orange, Lemon, Lime.
-2.5 cups of sour cream
-Dissolve the black cherry jell-o in 1 cup of boiling water. Divide the mixture in half and add 2 tablespoons cold water to one half and pour into a 9x13 pan. Put in the freezer for 8-9 minutes (make sure it is level).
-Add 1/2 cup sour cream to the other half of jell-o and mix well until well mixed. When clear jell-o is set add jell-o w/sour cream on top and put back into the freezer for another 8-9 minutes.
-Continue with the rest of the jell-o flavors. Layer in the order listed above ending with the Lime sour cream layer.
I suggest putting into a clear 9x13 pan as it looks really cool when all the layers are set-up. Enjoy!
