I remember reading about how steel-cut oats are made though time had lots that from my memory so I asked Mr. Google.
I am talking about why these oats are called "Steel-cut" Oats.
Mr. Google told me:
Healthline said, "How are steel cut oats made?
Steel cut oats are one of the least processed oat varieties. They're made by chopping hulled oat grains, or groats, into small pieces with a steel blade. This process keeps each part of the grain, including the bran, endosperm, and germ, mostly intact.
