- 2 (3 ounce) packages berry blue gelatin
- 2 (3 ounce) packages strawberry flavored gelatin
- 4 cups boiling water, divided
- 2 1/2 cups cold water, divided
- 2 envelopes unflavored gelatin
- 2 cups milk
- 1 cup sugar
- 2 cups sour cream
- 2 teaspoons vanilla extract
- In four separate bowls, dissolve each package of gelatin in 1 cup boiling water. Add 1/2 cup cold water to each and stir. Pour one bowl of blue gelatin into an oiled 10-in. fluted tub pan; chill until almost set, about 30 minutes.

When blue gelatin in pan in almost set, carefully spoon 1-1/2 cups sour cream mixture over it. Chill until almost set, about 30 minutes.
