The Wagyu Arm Roast, also known as a chuck arm roast, is packaged as one roast per package and typically weighs about 5 lbs.. This cut comes from the shoulder and is known for its rich beef flavor and connective tissue that breaks down beautifully when cooked slowly.
Arm roast should be cooked low and slow until fork tender. Cooking too quickly will result in a tough texture. Allow enough time for the connective tissue to fully break down.
