In a mixing bowl, cream shortening and sugar with an electric mixer. Beat in egg and molasses until well blended.
In another bowl, combine the flour, salt, baking soda and spices. Stir into the creamed mixture until blended. Chill for at least an hour, or until firm.
Roll the chilled dough into small balls about 3/4-inch in diameter. Roll each in the granulated sugar, and place on the baking sheet, leaving 1-2 inches between cookies.
Heat oven to 350 degrees. Prepare a baking sheet with parchment paper.
