Place in the oven and roast for 40 minutes, or until the potatoes are crisp and golden.

3. Season the steaks generously with salt and pepper and drizzle over a little oil. Work the seasoning into the steak using your finger tips. Place a frying pan over a high heat and add enough oil to coat the bottom of the pan. When smoking hot add the steaks. Cook for 2 - 3 minutes until a dark golden crust has formed then turn the steaks and cook for a further 2 minutes. Sear the  steaks along the  outside edges. Add the  butter to the pan and baste the steaks with the melted butter for a minute or two . Remove the steaks and place on a warm plate, cover loosely with foil and allow to rest for 5 min.

4. Serve the steaks with the potatoes and a generous dollop of Lucy's Truffle Mayonnaise.
