Chargrilled florentine T-bone

Method

1. Heat the oven to 220°C/fan200°C/gas 7. Put a griddle pan over a high heat. Brush the steaks on both sides with olive oil and season well with salt and pepper. When?the pan is very hot, cook the steaks on one side for 2-3 minutes until caramelised, then turn over and cook on the other side for 2-3 minutes (you may have to use two griddle pans or fry the steaks one after the other). Transfer the steaks to a large baking tray and put in the oven for 5 minutes. The meat will be medium rare.
2. Remove the steaks from the oven, then spread a knob of butter over each and squeeze over the lemon juice. Leave in a warm spot to rest for a few minutes.
3. Cut the meat away from the bones, then thickly slice. Arrange the meat on a platter or board, then scatter over the lemon zest, chopped garlic and rosemary, and drizzle with extra-virgin olive oil to serve.
