This is our go to family Sunday Aberdeen Angus Beef roast. Slather the top of it with a nice grainy mustard and cook for 15 mins per 500g in a hot oven. A 1.5kg joint should take approx. 50 mins on a high heat. Once its done, cover it with tinfoil and rest it for at least 30 mins while you make your gravy with the meat juices and some nice beef stock you’ve made with those beef marrow bones. Your joint won’t get cold, and it will only improve in tenderness. Slice it thinly, for a super tasty plateful of organic meat.
