A smoke plank for the barbecue gives fish, meat and vegetables on the barbecue a mild smoky aroma. Soak the plank in water beforehand, place the food on it and close the lid. Use smoke chips on the coals or in a smoke box on a gas barbecue for a stronger smoky flavour. A Himalayan salt stone works differently: you grill on it, and the food gets a light salty crust.
