Instructions

1. Cut 1 medium lime into 8 wedges and place 2 tablespoons red sanding sugar in a shallow dish. Use the lime wedges to moisten the rim of the punch glasses, then dip the glasses in the sanding sugar to coat the rim.
2. Place 4 cups cold water and 2 (.13-ounce) packets Lemon-Lime Kool-Aid or 1/3 cup Country Time lemonade drink mix in a large punch bowl. If using lemonade drink mix, add a few drops of green food coloring if desired. Stir until the mix is completely dissolved. Add 1 quart lime or rainbow sherbet a few scoops at a time, letting the sherbet slowly melt and incorporate into the punch.
3. Add 4 cups cold lemon-lime soda 1 cup at a time. The punch will foam up, but adding it slowly will allow it to dissipate and avoid overflowing the punch bowl. Ladle the punch into the glasses.
