    Best Cooking Methods for Sirloin

    Our Angus Sirloin Roast SB 2, known for its firm texture and rich flavour, excels in various cooking methods. The cut's fat renders beautifully, enhancing taste and tenderness. When preparing, consider these approaches:

    Pan Sear: Use medium-high heat for a crisp exterior. Allow the roast to rest for ten minutes to maintain juiciness.

    Grill: Opt for direct heat to seal in juices. Aim for medium-rare to preserve the rich flavour profile.

    BBQ: Utilize indirect heat for slow cooking. This method tenderizes the meat, making it ideal for gatherings.

    Oven: Preheat to 200°C for a golden crust and even cooking. A meat thermometer ensures preferred doneness without overcooking.

    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.

    Delivery & Packaging

    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.

    You can add these instructions in the “View Cart” section before checkout using the notes box or send them through to us via email.

    How is my order kept cold?

    We use specialist refrigerated courier partners to keep your order within the cold chain from dispatch to delivery. Each order is packed in a thermal carton lined with VISYCELL® sustainable insulation, a food-grade, biodegradable material designed to maintain a consistent chilled temperature throughout transit.

    We also include large 1kg ice gel packs in every box to help keep your products at optimal temperature. Our packaging has been tested to maintain safe temperatures for a few hours after delivery when left in a shaded area.

    My box arrived looking a bit scuffed. Is the meat okay?

    While the outer carton may show signs of handling during delivery, the internal insulation is specifically built to protect the contents and preserve freshness.

    What should I do if I have concerns?

    If you detect any issues with the temperature or seal of your products upon arrival, please contact our team immediately so we can find a solution for you.
