Subprimal cut is a section of meat fabricated from a larger primal cut during butchery. Subprimals are commonly supplied to restaurants as vacuum-packed, boneless or bone-in pieces for further trimming and portioning. Examples include strip loin, tenderloin, inside round, brisket, chuck roll and ribeye roll.
Meat fabrication generally follows a hierarchy: the carcass is divided into sides or quarters, quarters are broken down into primal cuts, primals are separated into subprimals, and subprimals are trimmed into individual portion cuts. The exact names and boundaries vary by animal species and national butchery system.
Buying subprimals can reduce the amount of fabrication work required in the restaurant while allowing chefs to control final trimming, steak thickness and portion weight. The choice between purchasing a whole subprimal and pre-portioned product depends on volume, labour, storage, equipment, yield and supplier pricing.
Example: a restaurant may purchase a vacuum-packed strip loin, trim it in-house and cut it into steaks of a standard weight and thickness.
Subprimal cost must be evaluated using usable yield, not simply the purchase price per kilogram. Fat, silverskin, bones and other trim reduce the amount of saleable portion product. Record the weight before and after trimming, the number of portions produced and the use of secondary trim.
Chef’s tip: specify the subprimal name, supplier item number, trim, bone status, grade, weight range and packaging when ordering. This improves quotation comparisons and recipe-cost accuracy.
Key distinction: A primal is a major carcass section; a subprimal is a smaller fabricated section from that primal; a portion cut is an individual piece prepared for cooking or service.
