4 cups sugar
13 cups water
3 (3-oz.) boxes peach gelatin (or flavor of your choice)
2 (46-oz.) cans unsweetened pineapple juice
1 tbsp lemon juice
2 (1-liter) lemon-lime soda, at room temperature
In a saucepan, mix sugar and 4 cups water, then bring to boil. Let cool. Dissolve gelatin in 3 cups boiling water and to that add 6 cups cold water. Add the above two mixtures together with the juice. Freeze until solid (approximately 2 days). Remove from freezer 2 to 3 hours before serving and pour the warm 7-Up over it. Mix until slushy.
