Mom's Ginger Molasses Cookies

I love these cookies and make them all the time. One of the few "roll" type cookies I will make throughout the year rather than just at Christmas.

3/4 cup butter or margarine

1 cup sugar

1 egg

2 teaspoons baking soda

2 cups flour

4 tablespoons molasses

1/2 teaspoon salt

1 teaspoon ginger

1 teaspoon cinnamon

Sugar

Preheat oven to 350 degrees.  Mix together all ingredients.  Roll into 1 inch balls and roll in small bowl of sugar.  Place on un-greased baking sheet and bake about 10 to 12 minutes.
