1 container of the mixed-flavored sherbert
1 2-liter bottle of ginger ale
1 can of frozen lemonade (pink is pretty)
water to taste
Recipe
Combine ginger ale and frozen lemonade in a large punch bowl. Open the container of sherbert and either scoop or slice it, putting it directly into the bowl. Cut the sweetness with cold filtered water to taste, or use equal amounts of water and more ginger ale.
This can be made with sprite or 7-up.
Every single party I've been to where this punch was served had a jello-mold ice ring (sometimes with frozen berries in the ice) floating in it, which cuts the sweetness as it melts.
