There is a lot more that goes into a delicious steak than just laying it on top of a wood fire and watching it cook. The right grilling technique can do a lot to unleash the flavor of a steak and other meat products.
There are several reasons why this is so. One is that a fire fueled by wood is often a lot hotter than flame produced by gas or charcoal; higher temperature cooks the meat more thoroughly, searing the steak so that the juices get locked in. Another reason is that smoke contributes to the flavor. Hickory and other woods lend their aroma to the meat, sometimes even making marinades and rubs unnecessary; when marinades are present, however, the taste becomes even more memorable.
