Heston’s barbecue tip
To intensify the smoky flavour of the meat, place wood chips in a square of tin foil, folding it round the chips to make a closed parcel. Using a sharp knife, poke holes in the parcel. When the barbecue has cooled down slightly, put the parcel on to the coals. Place the steaks on the grill and cover with the barbecue lid, allow to stand for 10 minutes, flipping after 5 minutes.
