Lime Milk Shake

I saw this recipe in Simple and Delicious and it just made my mouth water to think of it, but I couldn't find any Lime Sherbet at the store, so we came up with our own version and it turned out pretty good.

Lime Milk Shake
2-1/4 cups milk
3/4 cup limeade concentrate
3 cups lime sherbet, softened

Place all ingredients in a blender; cover and process until smooth. Pour into chilled glasses; serve immediately. (yield 6 servings)

Our version:
2-1/4 cup milk
3/4 cup passion punch concentrate
3 cups orange sherbet, softened
