Meat Glossary
51 terms defined by a 3rd-generation butcher — from primal cuts to wagyu grading.
Primal Cuts
Brisket
The chest primal cut, consisting of the flat and the point, prized for low-and-slow smoking and braising.
Chuck
The large primal cut from the shoulder and neck area of the steer, known for rich flavor and connective tissue.
Flank
The lean, flat primal cut from the abdominal area, known for its strong beef flavor and need for proper slicing against the grain.
Loin
The primal cut along the upper back behind the rib, producing the most tender cuts including tenderloin, strip steak, and T-bone.
Plate
The belly primal cut below the rib, yielding short ribs, skirt steak, and hanger steak — rich, beefy, and full of flavor.
Rib
The primal cut spanning ribs 6–12, yielding some of the most prized and tender steaks including ribeye and prime rib.
Round
The rear leg primal cut, very lean with large muscles suited for roasting, braising, or slicing thin for sandwiches.
Shank
The lower leg primal, extremely tough when raw but produces the most gelatinous, deeply flavored braises when slow-cooked.
Sub-Primal Cuts
Denver Steak
A well-marbled, tender steak cut from the serratus ventralis muscle in the chuck, discovered through the same muscle profiling studies as the flat iron.
Flank Steak
A lean, flat, intensely flavorful steak from the abdominal area with long visible grain fibers that must be sliced against the grain.
Flat Iron Steak
A tender, well-marbled steak cut from the chuck top blade, discovered via muscle profiling research as the second most tender cut of beef.
Hanger Steak
A thick, intensely beefy cut that "hangs" from the diaphragm — only one per animal — long known as the butcher's secret steak.
Picanha
A triangular cut from the top of the sirloin cap with a thick fat cap, hugely popular in Brazilian churrasco and gaining traction in the US.
Porterhouse Steak
A cross-cut from the rear of the short loin containing both a New York strip and a large tenderloin section, separated by a T-shaped bone.
Skirt Steak
A long, thin, heavily grained cut from the diaphragm area, available as outside skirt (superior) or inside skirt, and the classic cut for fajitas.
T-Bone Steak
A cross-cut from the short loin with a T-shaped bone separating a New York strip and a smaller tenderloin section.
Tomahawk Steak
A bone-in ribeye with the entire rib bone frenched and left attached, creating a dramatic handle that can extend 6–8 inches.
Tri-Tip
A triangular cut from the bottom sirloin, popularized in Santa Maria, California, with excellent flavor when grilled or roasted.
Cooking Methods
Braising
A slow, moist-heat cooking method using a covered pot with liquid, ideal for converting tough collagen-rich cuts into tender, flavorful dishes.
Grilling
A high-heat, dry cooking method using direct radiant heat from below, best suited for tender, well-marbled cuts.
Maillard Reaction
The chemical reaction between amino acids and sugars at temperatures above 280°F that creates the browned crust, complex flavors, and aromas of seared meat.
Resting Meat
Allowing cooked meat to sit undisturbed after cooking so that juices redistribute throughout the muscle, critical for a juicy result.
Reverse Sear
A two-stage cooking method where meat is slow-cooked at low temperature first, then finished with a high-heat sear for the crust.
Roasting
A dry-heat oven cooking method using indirect heat, ideal for large, tender cuts like prime rib and tenderloin.
Searing
Cooking meat at very high heat (500°F+) to create a browned, flavorful crust through the Maillard reaction.
Smoking
A low-temperature cooking method using wood smoke over many hours, transforming tough cuts through slow collagen breakdown and smoke flavor absorption.
Sous Vide
A precision cooking method using vacuum-sealed bags in a temperature-controlled water bath, allowing exact doneness control impossible with traditional methods.
Grading & Quality
BMS (Beef Marbling Standard)
The Japanese marbling grading scale from 1 to 12, used to evaluate wagyu beef, where BMS 12 represents the highest possible marbling.
BMS Score (Beef Marbling Score)
The Japanese 1–12 numerical scale used to objectively measure intramuscular fat in wagyu beef, where 12 is the highest possible marbling.
Certified Angus Beef (CAB)
A branded beef program requiring Angus-type cattle to meet 10 quality specifications, effectively guaranteeing upper USDA Choice or better.
Marbling
The visible flecks of intramuscular fat within the lean meat, the single most important factor in beef flavor, juiciness, and tenderness.
USDA Choice
The second-highest USDA quality grade, representing the majority of graded beef sold in the US, with moderate marbling.
USDA Prime
The highest USDA quality grade, representing approximately 8-10% of all graded beef, with abundant marbling throughout.
USDA Select
The third USDA quality grade, leaner than Choice with slight marbling, requiring careful cooking to avoid dryness.
Yield Grade
A USDA measurement (1-5) estimating the percentage of boneless, closely trimmed retail cuts from a carcass, with 1 being the highest yield.
Butchery Terms
Bench Scraper
A flat, rectangular tool with a sharp edge used for cleaning cutting boards, portioning dough, and transferring ingredients.
Breaking Knife
A heavy, long-bladed knife used for breaking down large cuts of meat, portioning, and general butchery work.
Butcher Block
A thick, durable cutting surface made from wood, typically used in professional and home kitchens for meat preparation and cutting.
Cryovac
A vacuum-sealed packaging method that removes air to extend shelf life and prevent oxidation, commonly used for meat storage and aging.
Dry Aging
The process of storing beef in a controlled environment (34-38°F, 80-85% humidity) for 21-120+ days to concentrate flavor and improve tenderness.
Fabrication
The process of breaking down a primal or sub-primal cut into retail-ready portions — steaks, roasts, and trim.
Grain (Muscle Fiber Direction)
The direction that muscle fibers run through a cut of meat, critical for slicing — always cut against the grain for tenderness.
Meat Thermometer
An instrument used to measure the internal temperature of meat during cooking to ensure proper doneness and food safety.
Primal Cuts
The eight major sections a beef carcass is initially divided into: chuck, rib, loin, round, brisket, plate, flank, and shank.
Seam Cutting
A butchery technique of separating muscles along their natural connective tissue boundaries rather than cutting through the muscle.
Silverskin
A tough, silvery-white membrane of connective tissue (elastin) that covers some muscles and must be removed before cooking as it never breaks down.
Wet Aging
Aging beef in its vacuum-sealed packaging at refrigerated temperatures, allowing enzymatic tenderization without moisture loss.
Wagyu & Japanese Beef
A5 (Japanese Beef Grade)
The highest grade in the Japanese beef grading system, combining the best yield score (A) with the highest quality score (5).
Fullblood vs Crossbred Wagyu
Fullblood wagyu is 100% Japanese genetics; crossbred (F1–F4) is wagyu crossed with another breed, with each generation increasing the wagyu percentage.
Kobe Beef
A specific brand of wagyu from Tajima-strain Japanese Black cattle raised in Hyōgo Prefecture, Japan, with strict certification requirements.
Wagyu
Japanese cattle breeds (wa=Japanese, gyu=cattle) genetically predisposed to extraordinary intramuscular fat, including Japanese Black, Brown, Shorthorn, and Polled.
