Lime Fruit Slushies

Ingredients:
3/4 cup sugar
1 package (3 oz) lime gelatin
1 cup boiling water
3 cups cold water
3 cups unsweetened pineapple juice
1 can (6 oz) frozen orange juice concentrate, thawed
1 liter ginger ale, chilled

In a large container (I use an ice cream pail with lid), dissolve sugar and gelatin in boiling water. Stir in the cold water, pineapple juice and orange juice concentrate. Freeze. Remove from the freezer about 1-2 hours before serving. Stir in the ginger ale just before serving.
