6 (3 oz. ea.) boxes Jello (regular or sugar-free)
1 (16 oz.) carton sour cream

Level your refrigerator. Cool a 9x13-inch Pyrex pan in the refrigerator for a few hours. Dissolve 1 box Jello in 1 cup boiling water. Divide in half. To one half, add 3 tablespoons cold water and pour into chilled pan. Return to refrigerator and let set about 1/2 hour. To the other half add 1/3 cup sour cream. When clear layer is set, pour this layer on top. Let set about 1/2 hour. Repeat steps with another box of Jello. Keep adding layers, alternating clear and creamy.

Cover with plastic wrap when it is finished and store in refrigerator.
