Heat oven to 350 degrees. Grease 15 medium muffin cups (2-3/4 in. diameter). Mix thoroughly shortening, 1/2 cup sugar, egg. Stir in flour, baking powder, salt and nutmeg alternately with the milk. Fill the muffin cups 2/3 full. Bake 20-25 minutes. Topping: Mix 3/4 cup sugar and the cinnamon. Immediately after baking, roll puffs in melted butter, then in cinnamon-sugar mix. Serve hot. These are very light in texture. Great taste!
