Rump Roast
Rump roast is a beef roast cut from the rear corner of the round primal where the round meets the sirloin. It is more flavorful than top round but slightly tougher because of more developed connective tissue. The traditional preparation is pot-roasting or braising; modern slow-cooking and sous-vide methods make excellent medium-rare slicing roasts from it as well.
Anatomy and naming
What this cut actually is
The rump section sits at the boundary between the sirloin and the round, and the cut takes muscle from both primals depending on local butchery. US rump roast is bottom round near the sirloin junction; UK silverside includes a similar region. The cut has more connective tissue than top round but more flavor, which is why pot-roasting (slow moist heat) is the historical preparation, the connective tissue dissolves into gelatin and the lean stays moist.
For modern slow-cook preparations, rump roast holds up very well at low temperatures: 110°C / 225°F oven or sous-vide at 56°C / 133°F for 12 hours produces a medium-rare slicing roast with the connective tissue partially broken down. The leftover fat and tendon-like seams should be trimmed before slicing.

How to spot a good one
Visual markers
A wedge-shaped or rounded roast, denser than top round
Visible connective-tissue seams running through, more than top round
Bright deep-red lean color
A thin to moderate fat cap on one face
Some surface marbling, less than loin cuts but more than eye of round
Cooking, on Pro
Cook rump roast like its grade
MeatGrader Pro gives you a cooking guide tailored to the exact cut and quality grade in front of you. Temperature, time, primary and alternative methods, resting, pairings.
A USDA Prime rump roast gets a different guide than a Choice rump roast, and an A5 BMS 9 wagyu cut gets something else again. Generic recipes do not know which one you have. Pro does.

How it grades
Grading rump roast
Rump roast carries the carcass grade with the same caveat as other round-primal cuts: marbling is intrinsically sparse. MeatGrader reads the grade primarily off color, grain, and the relative quality of any visible intramuscular fat. The connective-tissue pattern is also informative, finer, more evenly-distributed seams indicate younger or higher-grade animals.
