Snickerdoodles
One of the basics of cookie recipes. For cinnamon sugar, take 1 cup of sugar and start out with 1 t of cinnamon, adding more or less as your tastes desire.

Preheat oven to 350°F.

Cream shortening with sugar until light. Add in eggs one at time, mixing well after each addition. Sift together the flour, cream of tartar, baking soda and salt. Add to creamed mixture, then cover and chill dough for 1/2 hour or until firm enough to handle. Gather walnut-size pieces of dough and roll into a ball. Roll each ball in cinnamon sugar and place on baking sheet about 2 inches apart. Bake for about 10 to 15 minutes, or until light brown. The tops will be cracked, and you want the centers to be soft, so don't overbake. Let rest on baking sheet 3 minutes before transferring to cooling rack.
