Place lime sherbet into your punch bowl. This is best done using an ice cream scoop, so the sherbet will be evenly distributed.
1 quart lime sherbet
Pour the Sprite (or carbonated beverage of your choice) over the lime sherbet.
12 cups Sprite
Add three drops of food coloring and stir. You can add more if you prefer a brighter green color.
3 drops green food coloring
Garnish with lime slices or mint and enjoy!
Lime slices or mint leaves for garnish
Notes
Be sure to chill the Sprite before serving. Otherwise, the sherbet may melt too quickly.
Right before serving, give the punch another stir, making sure to break up any large clumps of the lime sherbet. This will help ensure that there will be a scoop of sherbet in every single serving.
