The Bikers says: “This simple classic takes skill to get exactly right. Si and Dave show you how, with precision-cooked meat.”

For the steak: 4 x 275g sirloin or rib-eye steaks, at room temperature, splash groundnut oil, or similar flavourless oil, salt and freshly ground black pepper, large knob of butter and watercress, to serve.
