Common oat products include steel-cut oats, oatmeal and rolled oats.
Steel-cut oats are the whole grains (called groats) chopped into 2 or 3 pieces. They are also known as 'pinhead oats'. These oats take the longest to cook of the processed oat products. They have a chewy texture and keep their shape after cooking. Porridge is a popular use.
Oatmeal is oat grains milled to varying grades: coarse, medium or fine. Its uses include porridge and baking, such as oatcakes.
Rolled oats are cut oats that have been steamed and then flattened by rollers. They are also called 'oat flakes'. Because they have been heat-treated, they cook more quickly than oats that have only been milled. They are used for porridge, breakfast cereals such as muesli, and baking.
