When I decided to make a cranberry/apple pie for this year's Thanksgiving dinner, I found a bunch of recipes online. But none of them really hit home with me. Also, I'm sorry Martha Stewart, but after reading the recipe notes on Cook's Illustrated, I decided that just tossing the cranberries in with the apples didn't sound right.

Whether you use a rolling pin, a wine bottle, or a glass, always roll the dough from the center out in all directions. Don't go back and forth. Roll the dough to 1/8 inch thickness or less. Don't worry if you have a few tears. You can patch them later.
