Beef brisket flat half boneless comes from the brisket (breast) section and is cut from the rear portion of lean meat and the fat closest to the plate layers with the breast and rib bones removed. It is usually prepared by cooking in a crock pot, smoked long, low, and slow, or cured in salt brine to make corned beef brisket. It has a rich, beefy flavor. Because it is from grass-fed beef, its richly flavored fat is very good for you as it almost always contains more Omega-3 fatty acids than Omega-6 fatty acids. Palatability is improved when the Brisket is sliced across the grain. U.S. raised grass-fed beef.
