1 cup powdered sugar
1 cup butter or margarine -- softened
1 tablespoon white vinegar
2 1/4 cups all-purpose flour
1 1/2 teaspoons ground ginger
3/4 teaspoon baking soda
1/4 teaspoon salt
6 drops red food color
Heat oven to 400∫. Beat powdered sugar, butter and vinegar in large bowl with electric mixer on medium speed, or mix with spoon. Stir in remaining ingredients except food color. Divide dough in half. Mix food color into one half. (If dough is too dry, stir in milk, 1 teaspoon at a time.)
Roll dough 1/8 inch thick on lightly floured cloth-covered surface. Cut into heart shapes with various sizes of cookie cutters. Place smaller hearts on larger hearts of different color dough if desired. Place about 2 inches apart on ungreased cookie sheet.
Bake 5 to 7 minutes or until set but not brown. Cool 1 to 2 minutes; carefully remove from cookie sheet to wire rack. Cool completely. Decorate with white and pink Decorator's Frosting if desired.
