How To Butcher An Entire Cow: Every Cut Of Meat Explained | Bon Appetit

For any professional kitchen, whole-animal butchery—or at least primal-cut fabrication—is an invaluable skill that drastically improves yield, menu versatility, and profit margins. In this demonstration, Jason Yang of Fleishers Craft Butchery showcases the systematic breakdown of a side of beef, dividing it into the four foundational primals: the round, loin, rib, and chuck. Understanding where these muscles sit on the carcass is essential for any chef wishing to source more sustainably and master carcass utilisation.

Systematic Breakdown of the Four Primals

Yang’s approach begins at the rear of the animal with the round. This lean, hard-working section yields cuts like the bottom and eye round roasts, the sirloin tip, and the shank, which is perfect for slow-braised applications like osso buco. Moving into the loin, chefs are introduced to the highly prized, tender cuts including the sirloin, tenderloin, flank, and New York strip. Here, the technique focus shifts to precision slicing and seam-following to preserve the shape and texture of these high-value muscles.

The rib primal follows, showcasing the isolation of the highly marbled ribeye and the fibrous, flavourful skirt steak. Finally, the chuck—or shoulder region—is broken down. This section is a treasure trove for modern menus, yielding not just traditional roasting joints and brisket, but also increasingly popular secondary cuts like the flat iron, denver, and ranch steaks.

Key Techniques and Pitfalls to Avoid

The primary lesson for culinary professionals is the importance of seam butchery. Rather than sawing straight through muscle groups, Yang demonstrates how to follow the natural seams of fat and connective tissue. Failing to do so is a common pitfall that damages the muscle fibres, leading to uneven cooking and tough meat.

Additionally, chefs must learn to categorise cuts by their structural properties. High-use muscles from the chuck and round require low-and-slow cooking techniques to melt collagen, whereas the underworked muscles of the loin and rib are suited to high-heat, rapid cooking methods like pan-searing and grilling. Mastering these distinctions allows kitchens to minimise waste and transform cheaper cuts into premium menu highlights.
