A hamper from dp's work has just arrived with a rib of beef with 5 ribs weighing 5.7kg. I've already cooked our gammon for tomorrow so apart from veg the oven will be free. We have extra guests due to the weather so I want to cook the joint of beef but have no idea how / how long for etc. It is from Fortnum and Mason but doesn't have any cooking guidance on it.
I like my meat medium but think most of dp's family will want it burnt.
Any tips very much appreciated. Have a large selection of herbs, onions, garlic, oil, stock etc.
