3 c. water
2 c. sugar
3 ripe bananas
1 (46 oz.) can pineapple juice
1 1/2 c. orange juice
1/4 c. lemon juice
3 qt. ginger ale (8-10 12 oz. cans)

Mix a small amount of pineapple juice and orange juice with the bananas in a blender until smooth. Add the rest of the juices and blend until smooth. Mix the water and sugar in a pan and bring to a boil. Cool. Add to juice mixture.

Freeze in 6 ice cube trays, plus a small amount in another container. When ready to serve, set out half an hour and pour ginger ale on top. Three trays plus four 12-ounce cans ginger ale make 6 quarts.
