In a large bowl, use an electric mixer to beat together shortening, sugar and eggs.
In a separate bowl, sift dry ingredients together and stir into wet mixture. Chill dough in refrigerator until firm, at least 1 hour.
Preheat the oven to 375℉.
In a small bowl, mix the sugar and cinnamon. Use your hands to roll cookie dough into small balls (about 1½ tablespoons each). Roll balls in the sugar/cinnamon, and place on an ungreased baking sheet, about 2 inches apart
Bake for 8 to 10 minutes until cookies are flattened and look crinkly. Let cool on cookie sheets at least 5 minutes, then remove to a wire rack to cool completely.
Notes
For the rolling sugar: You'll have leftover sugar to throw away after rolling. I call for more than needed because I like to have a good puddle to roll them around in. Use less sugar if you don't want the waste.
