Preheat the oven to 350 degrees F.
Line cookie sheets with parchment paper or nonstick baking mats. Using an electric mixer at low speed, cream the shortening and sugar until thoroughly combined. Add the egg and molasses and beat until completely incorporated. Sift together the flour, baking soda, cinnamon, ginger, cloves and salt and add to the mixture. Stir until combined. Roll the dough into balls about 1-inch in diameter. Roll the balls in sugar. Place 1/2-inch apart on the prepared cookie sheets. Flatten the balls slightly with your fingertips. Bake for 12 minutes. Cool on wire racks.
