Ingredients

For the cookies:
1 cup butter or margarine, softened
1 cup sugar
1 egg
2 cups flour
1 teaspoon grated lime peel
1 cup finely chopped pistachios

For the lime icing:
2 tablespoons butter or margarine
1 cup powdered sugar
1 tablespoon milk
1/4 teaspoon grated lime peel

Directions

Cream butter and sugar; beat in egg. Stir in flour and lime peel; mix in pistachios. Refrigerate dough 1 hour. Preheat oven to 375F. Roll dough 1/4 inch thick; cut shapes with cookie cutters. Place on ungreased baking sheet. Bake 8 to 10 minutes or until lightly browned; cool. Pipe icing to outline cookies.

Lime Icing:

Beat butter with powdered sugar, milk, and lime peel until smooth. If frosting is too stiff, beat in a few drops more milk; if too soft, beat in more powdered sugar. Makes about 1 cup.
