Preheat the oven to Gas mark 4-5, 180-190°C, 350-375°F.

Take the beef joint and calculate the cooking time according to your preference. Season and place into a roasting tin. Open roast in a preheated oven for the calculated cooking time.  Add the onions and garlic to the pan around 25- 30 minutes before the end of cooking time. When the joint comes out of the oven, allow it to rest for a minimum of 15 minutes before carving

Increase the oven temperature to Gas mark 7, 220°C, 425°F for the Yorkshire puddings: In a bowl mix together t.he flour and eggs, then add the beer and whisk until smooth. Divide the oil between 4 large or 12 small Yorkshire pudding tins and heat in the oven for 5-10 minutes. Pour the batter in the heated tin and cook for 20-25 minutes until risen and browned.

Serve the beef with the Yorkshire puddings, onions (or add to the gravy) roast potatoes and seasonal vegetables.
