This classic roast sirloin of beef is the ultimate centrepiece for a family gathering or a refined Sunday lunch. By searing the meat in a hot frying pan before roasting, you lock in the natural juices and develop a rich, savoury crust that beautifully complements the tender, pink middle. Using high-quality grey sea salt and cracked black pepper enhances the premium cut without the need for heavy sauces, keeping the dish elegant and focused on the quality of the beef.
