USDA Prime Chuck RoastNot your average pot roast. This is USDA Prime the highest grade awarded for marbling and tenderness and exceptionally rare in a chuck roast. Most chuck in the market is Choice. Ours is richly marbled Prime Black Angus beef, averaging between 2 3 lbs and packed with deep, beefy flavor. Smoke it like a mini brisket. Braise it low and slow. Cube it for burnt ends. This is the cut serious cooks keep in their freezer.
