Lime Sherbet Punch - cooking recipe

Ingredients

4 liters ginger ale
2 liters 7-Up
1/2 gal. lime sherbet (rectangular box)

Preparation

Ahead of time, cut 1/2 gallon sherbet into three sections and freeze separately.
Freeze some ginger ale in a mold to create a solid ice ring to float in punch.
(This keeps punch from being watered down from a regular ice ring.)
