The fuel used for smoking may contain flavoring adjuncts. For example, Chinese tea-smoking uses a mixture of uncooked rice, raw sugar, and tea, heated at the base of a wok, to slowly smoke and flavor meat and other foods. In Europe, the traditional wood burnt to smoke fish and meat is alder, but oak is more often used now, and beech to a smaller extent. In North America, hickory and mesquite wood are commonly used for smoking.
