This elegant little Italian grain grinder has three hardened steel rollers that flatten grain for making flakes or crack it for making hot cereal or granola. I’d never had fresh oats before until my friend showed me this device, just after he gave me a breakfast bowl of fresh oatmeal along with flax seeds, shredded coconut, a little hemp oil for flavor, and brown sugar. As you grind oats you’re taking the whole oat grain (groat), and crushing and flaking it just before you cook it. You get nutty, delicious oatmeal, the flavor of the whole grain just released. Clamps to any surface up to 2″ thick.
