6 or 7 packages of 3 oz. jell-o
1 pint of sour cream
Whipped topping for the top
Add 1 cup boiling water to 1 package of Jell-O in a small bowl; stir to dissolve. Pour half of Jello into a 9x13 clear pan and place on a level self in the refrigerator to chill. Set the small bowl with the other half of the dissolved Jell-O into a larger bowl of ice. (I just added one ice cube to it while the first half set). When the layer has set in the pan, the icy jell-o will be syrupy (it doesn't take long since quantities are small). Add a heaping tablespoon of sour cream to the Jell-O on ice, (I forgot the ice sometimes and it still worked), and mix until smooth. Pour this over the clear set jell-o. Return to refrigerator; when set, repeat using contrasting color of Jell-O. The book says that green is a good color to start with.
When you're all done with that, cover with a layer of whipped topping.
Cut in squares and serve. Keep it chilled.
Note: Each layer should be set only enough to hold the next layer. If set too hard, the layers will not bond well and may slip when served.
Another Note: I went to church between layers and they bonded fine. I'm just writing what's in the book.
