This is a very refreshing dish from my friend, Joyce Church.
Dissolve a 6 ounce box of orange Jell-o in 2 c. boiling water. Add 1 1/2 c. cold water. Mix well and set aside. Cook a 6 ounce box of cook-to-serve lemon pudding as the package directs. Add to Jell-o and whisk until well mixed. Pour into a 9 x 13" dish and refrigerate until set. Top with Cool Whip and mandarin oranges. You can also use raspberry Jell-o with fresh raspberries or strawberry Jell-o with fresh strawberries.
