These are wonderful when you make them - and even better the next day! They look puffy in the oven but will settle down once they start cooling. Let them cool before you serve them.
In a medium bowl, with a mixer cream together the shortening, vanilla and 1 1/2 cups sugar. Mix in the eggs. Sift together the flour, baking soda, cream of tartar, and salt. Stir flour mixture into the creamed mixture until well blended. In a small bowl, stir together the 2 tablespoons of sugar, and the cinnamon.
Roll dough into walnut sized balls, (or use a scoop to form them) then roll the balls in the cinnamon-sugar mixture, making sure you have a generous amount on each ball. Place balls onto the prepared cookie sheet, about two inches apart.
Bake for 9 - 10 minutes in the preheated oven. Edges should be slightly brown. Centers will be puffy initially when removing from the oven. Once slightly cooled remove from sheets to finish cooling on wire racks. Let cool complete before serving.
These cookies will keep up to 2 days, stored in an airtight container or plastic freezer bag. (Good luck - these cookies only last HOURS in my house!)
Don't expect these to brown before you take them out of the oven - if they're brown, you overcooked them. Make sure you use butter-flavored Crisco and not real butter. As odd as it may sound, Crisco actually works better than real butter in many cookie and pastry recipes.
