Best Cooking Methods for Sirloin
Our Wagyu Sirloin Whole SB 8-9, with its high marble score, excels in fat rendering and requires precise cooking methods to achieve optimal tenderness and flavor. When preparing our Wagyu Sirloin, consider these methods to enjoy the best steak experience:
Pan Sear: Use medium-high heat for 3-4 minutes per side. Allow the natural marbling to render, enhancing the taste.
Grill: Set to high heat, cook 4-5 minutes per side. Direct flames bring out the sirloin’s deep flavors, with a perfect char.
BBQ: Maintain a medium heat, cook for 5-6 minutes each side. This method locks in juices, maintaining the Wagyu's signature tenderness.
Oven: Preheat to 180°C, roast for 10-12 minutes. Finish with a high-heat sear to the crust while keeping the inside succulent.
Enable your culinary skills to shine by selecting the Wagyu Sirloin Whole SB 8-9, ensuring each meal is a memorable delight.
Striploin
Striploin, also known as Sirloin, New York Strip, or Porterhouse (when bone-in), is a premium cut prized for its bold flavour and balanced tenderness. It comes from the short loin of the cow and features a fine grain with a satisfying bite. It's a favourite among chefs and home cooks alike for its generous marbling and robust, beefy taste.
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.
