2 1/2 cups of sugar
6 cups water
2 (3 oz) packages strawberry jello
1 (46 oz) can pineapple juice
1 qt (4 cups) orange juice
2/3 cup lemon juice
2 (2 liter) bottles lemon-lime soda
In large saucepan, combine sugar, water, and jello mix. Boil for 3 minutes. Stir in pineapple, orange and lemon juice. Divide mixture in half and freeze in two separate containers.
When ready to serve, place the frozen contents of one container in punch bowl and stir in 1 bottle of soda until slushy.
This has a LOT of sugar! If you're making this for kids, you can use the full amount. For adults, I'd cut it in half. And if you like it on the tart side, you could just use 1 cup of sugar.
Don't freeze more than 24 hours. If you have to make sure you remove frozen contents at least an hour or two before serving.
I used a potato masher to mash into slushy and worked GREAT.
