    Best Cooking Methods for Rump Cap

    Cooking the Black Onyx Rump Cap Whole SB-3 brings out its rich flavours through methods that accentuate its marbling and texture. Our rump cap's fat cap renders beautifully when cooked, enhancing tenderness and flavour. To achieve the ideal doneness, use heat carefully and allow the roast to rest, ensuring a satisfying eating experience.

    Pan Sear: Use medium-high heat to sear our Black Onyx Picanha Whole SB-3. Sear each side for 3-4 minutes to develop a caramelised crust, then let it rest for 5 minutes for the best tenderness.

    Grill: Preheat the grill to high. Cook our whole Black Onyx Rump Cap with the fat side down first, allowing fat to render. Flip after 8-10 minutes, grilling to the preferred doneness.

    BBQ: Set the BBQ to medium heat. Slowly cook the Black Onyx Rump Cap Marble Score 3, turning occasionally. Use indirect heat for even cooking and rest for 10 minutes before slicing.

    Oven: Preheat to 180°C (350°F). Roast our Black Onyx Rump Cap with Fat Cap for 20 minutes per 500g, ensuring the fat renders and enhances flavour. Let it rest for 10 minutes post-cooking to maintain juiciness.

    Rump

    Rump steak is a lean, flavourful cut taken from the hindquarter of the animal. Known for its firm texture and bold beef taste, it’s a versatile favourite that performs well on the grill, in stir-fries, or as a roast. Cut thick for steaks or diced for hearty meals, rump offers value without compromising on quality.
