C is for Cookie! But whose recipe is good enough for you? Around my house, my chocolate chip cookies are in high demand at Christmas time. They're a little different every time — I prefer them puffy and pretty, as a baker, but my family loves the flat ones that get all crispy around the edges. I know I'll probably get the former with extra flour, and the latter with ten tons of butter, but there's actually a lot of science determining how my dozens turn out. So how do you like your cookies? Ashley's an extra-salt-easy-on-the-chips girl, and me, I have yet to meet one I didn't like. What's your secret for the perfect batch every time?
