What is Steel-cut oats?

Steel-cut oats , also called pinhead oats, coarse oatmeal , or Irish oatmeal are groats of whole oats which have been chopped into two or three pinhead-sized pieces. The pieces can then be sold, or processed further to make rolled oat flakes, of smaller size than flakes of whole groats. Steel-cutting produces oatmeal with a chewier and coarser texture than other processes.

Steel-cut oats, and other types, are traditionally used to make porridge. They take longer to cook than instant, ground, or rolled oats, typically 15–30 minutes for porridge. Steel-cut oats are described as being nuttier and chewier than other types of oats. They can be used to make oatcakes, blended uncooked in smoothies and for other culinary purposes.
