Corned beef is a type of salted and cured beef that is usually made from brisket or round cuts of beef. It is often served as a cold cut, but can also be cooked in dishes such as corned beef HASH. The term 'corned' refers to the large-grained rock salt, or 'corns, ' used to cure the beef. HASH is a dish consisting of diced or chopped meat, potatoes, and other vegetables, all cooked together and served with gravy.
