Melt shortening in a 3 or 4-quart saucepan over low heat. (I melt shortening in a glass mixing bowl in the microwave). Allow to cool. Then add sugar, molasses and egg; beat well. Add flour, soda, cloves, ginger, cinnamon and salt and mix well. Chill thoroughly. Form into one-inch balls, roll in sugar and place on greased cookie sheet two inches apart. Bake at 375 degrees for 8 to 10 minutes. Makes 4 dozen cookies.
