The ribbons of color are especially attractive at holiday time. 3/4 c. boiling water for each pkg. Jello 3/4 c. cold water for each pkg. Jello 2 c. milk (scalded) 3/4 c. sugar 2 env. unflavored gelatin 1/2 c. cold water 1 pt. sour cream 1 tsp. vanilla
Dissolve each package Jello separately in boiling water. Add cold water. Set aside and don't refrigerate. Put 1 flavor Jello in 9x13 pan and refrigerate 45 minutes. Thereafter alternate layers every 30 minutes.
Sour cream mixture: Scald milk, add sugar. Dissolve unflavored gelatin in 1/2 cup cold water, then add it to hot milk. With electric mixer blend the milk and gelatin mixture into the sour cream. Add vanilla and mix thoroughly. Don't refrigerate this either. Use approximately 1 1/2 cups of this for each layer.
Can be halved: Use only 2 flavors of Jello - alternating, of course.
For filling: 1 cup milk, scalded; 1/3 cup sugar; 1 envelope unflavored gelatin, 1 cup sour cream, 1/2 teaspoon vanilla.
