    Best Cooking Methods for Rump Cap: Pan Sear, Grill, BBQ or Oven

    Cooking our Wagyu Rump Cap Whole SB 8-9 requires understanding how the fat cap enhances flavor and tenderness. Fat rendering is crucial for achieving the signature melt-in-your-mouth texture, while resting post-cooking ensures juiciness. Aim for medium-rare to medium doneness to savor its rich Wagyu flavor.

    Pan Sear: Use high heat to quickly sear our Wagyu Rump Cap, which locks in juices and enhances the buttery texture. Finish in the oven for even cooking.

    Grill: Preheat to medium-high to allow the fat to render and grill the Wagyu Rump Cap for six minutes per side. Let it rest for that ultra-buttery texture.

    BBQ: Maintain a medium heat for slow cooking, which ensures the fat cap melts evenly, infusing the Wagyu Rump Cap with its rich flavor.

    Oven: Roast at a low temperature to gently render the fat and develop a tender bite. Rest before slicing for the best Wagyu experience. 

    Each method highlights the unique qualities of our Wagyu Rump Cap, ensuring a luxurious dining experience.

    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.

    Frequently Asked Questions

    Our Beef

    Where does our beef come from?

    All of our beef is from our parent company Stanbroke Beef. This is important as the quality of the beef and ultimately your eating experience is determined by the care that has been shown to the animal during each stage of the production process. Any undue stress the animal experiences at any stage of its life is detrimental to the beef it will produce.

    As Stanbroke owns and operates each stage of the production process, strict best practices are followed to ensure the animals always receive the highest of care and that’s why at Peter Augustus we can guarantee the quality of our product each and every time.

    SB Marble Scores

    What is an SB Marble Score?

    The SB Score measures intramuscular fat (the white flecks in the meat). Higher scores mean more marbling, which results in superior tenderness, juiciness, and a richer, buttery flavour.

    Which score should I choose?

    • SB 0–2: Leaner, traditional beef flavour with a robust texture.
    • SB 3–5: Our "everyday premium" level; a perfect balance of flavour and tenderness.
    • SB 6–10: The indulgent peak, featuring extreme marbling for a melt-in-your-mouth experience.

    Meat Quality & Colour

    What is vacuum sealing and how does it extend shelf life?

    Vacuum sealing removes air from the packaging, slowing oxidation and bacterial growth to extend freshness and shelf life. When stored correctly at 0–4°C, you can expect the following guide:

    • Beef primals & whole cuts: up to 28 days
    • Beef (steaks): up to 21 days
    • Beef (bone-in): up to 14 days
    • Lamb: up to 28 days
    • Pork: up to 10 days
    • Ham: up to 30 days
    • Sausages: up to 9 days
    • Chicken (frozen): up to 12 months
    • Salmon (frozen): up to 12 months
    • Smoked salmon: up to 30 days

    For longer storage, keep products frozen at -18°C, where vacuum sealed meat can last 1 to 3 years depending on the cut and consistency of temperature.

    Once opened, the shelf life reverts to that of standard fresh products, so we recommend consuming promptly.

    For longer delivery routes, some items may arrive partially or fully frozen to ensure they remain within safe temperatures during transit.

    Why is my steak dark in the vacuum pack?

    Our beef is vacuum sealed to lock in freshness and extend shelf life by removing oxygen. This can cause the meat to appear darker or slightly purplish due to natural myoglobin, which is completely normal.

    Once opened, simply let your steak rest out of the packaging for 10 to 20 minutes. As it’s exposed to air, it will “bloom” back to its natural rich red colour. Rest assured, your beef is fresh and perfectly safe to enjoy.

    Is it safe to eat?

    Yes. If the “Use By” date is within range your meat is fresh. Any colour variation from vacuum sealing is normal and will return to its natural red once opened and allowed to bloom.

    Can I request custom cutting instructions?

    Yes, our butchers are happy to accommodate custom cutting requests where possible and safe to do so. For example, you may like a rump cap portioned into steaks. Simply specify your preferred thickness or weight per piece, such as approximately 2.5cm or 300g portions.

    How is my order kept cold?

    We use specialist refrigerated courier partners to keep your order within the cold chain from dispatch to delivery.
