Rolled Oats are created when oat groats are steamed and then rolled into flakes. This process stabilizes the healthy oils in the oats. These stay fresh longer and help the oats cook faster by creating a greater surface area. Rolled Oats are a whole grain that can be used as a breakfast cereal like the various forms of oatmeal, rolled oats and pinhead oats that can be cooked to make porridge. These are used in granola, muesli, oatcakes, and flapjacks.
