Sugar Cookies
½ c. butter
½ c. margarine
½ c. sugar
½ c. powdered sugar
1 egg
1 ½ tsp. vanilla
2 tsp. lemon zest (optional)
½ tsp. baking soda
½ tsp. cream of tartar
2 ½ c. flour

Cream together first four ingredients.  Add egg, vanilla and lemon zest (optional).  Beat well.  Add remaining dry ingredients and mix well.  Divide dough, flatten on plastic wrap, wrap, and chill for 3 hours.  The chilled, flattened dough will make for easier rolling.  Roll out dough, cut, and bake at 375⁰ for 8 to 10 minutes or until cookies are light yellow around the edges.  Makes 2 to 2 ½ dozen.
