Preheat Your Oven

I'm working my way through Martha Stewart's "Cookies: The very best treats to bake and share." I will be making one batch of cookies each week. Since there are 175 recipes in the book, I plan on making cookies for several years (3.3, if I stick to the plan).

If you want to play along, I'm starting with 'Chunky Peanut, Chocolate, and Cinnamon Cookies' on page 179.
