1 12 ouncecan of frozen limeade, mixed according to directions
3cupssugar
8cupswater, in addition to the water you will add to the limeade concentrate
Juice of 6-7 limes, about 1/2 to 3/4 cup
1-2drops green food coloring
10-12ouncecups, about 30
1 2 literbottle lemon-lime soda
Instructions
The day before serving: Mix first 5 ingredients together in a large container. Stir until all sugar is dissolved.
Freeze overnight or until completely solid.
Take mixture out of freezer about 1/2 hour before serving and place on counter to thaw slightly.
When ready to serve, use a large serving spoon to scrape the frozen mixture into cups.
Fill with frozen limeade to top of cup. Slowly pour in soda until cup is filled.
Notes
Freezing the limeade in a deeper container will make it easier to scrape out. Using two to three 9x13-inch pans will help the limeade freeze faster.Use diet grapefruit soda in place of the lemon-lime soda to reduce sugar content.
