1. Pour the frozen limeade concentrate in a large bowl and add the Sprite. I like my punch on the tart side so I add about 3/4 of a bottle of Sprite. Add ice, sliced limes, and frozen raspberries if desired.
2. Got Sonic Fever? Turn it into cherry limeade by adding the juice of 1 (10 ounce) jar of maraschino cherries. Add an additional can of frozen limeade for some extra tartness and garnish with the reserved maraschino cherries.
