You can buy most nuts -- including walnuts, pecans, peanuts, and almonds -- already chopped (often labeled as "pieces"). If you buy whole nuts, you can chop them the size the recipe specifies (see photo) using a food chopper, chef's knife, or food processor -- just be sure to use a quick start-and-stop motion on the machine.Nut-Chopping 101
