This one sounded good to go with the Sherbert:

Gingered Lemon-Lime Fizz Recipe
Ingredients:
1/2 cup lemon juice
1/4 cup lime juice
2 cups cold water
4 teaspoons honey
2 cups ginger ale
4 thin lime slices (optional)


Directions:

In a 2-quart pitcher, combine the lemon juice, lime juice, water, and honey and set aside.

Fill 4 12-ounce glasses with ice cubes, divide the lemon-lime juice mixture among them, then top with the ginger ale. Stir briskly and put a lime slice, if you like, in each drink.

I'll have one with some lime sherbert, please!
