Mathews Butcher Grass Fed Beef Brisket | Approx. 1KgGrass Fed Beef Brisket (Approx. 1Kg) The Brisket is the king when it comes to low and slow beef cuts. The long cooking time allows for the for the connective tissue to break down. The unique thing about this cut of beef is that it can be slow cooked so its fork tender, yet is still sliceable.
