Preheat oven to 375 degrees Fahrenheit. In the bowl of an electric mixer cream together shortening, sugar, egg and molasses. In a separate bowl, stir together baking soda, salt, cinnamon, cloves, ginger and flour. Add flour mixture to wet mixture and mix to incorporate. Scoop or roll dough into 1 1/2" balls and place on Silpat mat or greased cookie sheet 2" apart. Press dough balls down slightly with the palm of your hand. Bake for approximately 6 minutes and at most 8 minutes. Don't over bake or they won't be soft! Don't let the bottoms get too brown. They should be a light golden brown. Let cool slightly, then remove to a cooling rack. Stir together powdered sugar and milk and drizzle over cookies. Store in an air tight container.
