Steaming

Steaming works by boiling water continuously, causing it to vaporize into steam; the steam then carries heat to the nearby food, thus cooking the food. The food is kept separate from the boiling water but has direct contact with the steam, resulting in a moist texture to the food. This differs from double boiling, in which contact with steam is undesired.

Such cooking is most often done by placing the food into a steamer, which is typically a circular container made of metal or bamboo. The steamer usually has a lid that is placed on the top of the container during cooking to allow the steam to cook the food. When a steamer is unavailable, a wok filled less than half with water is a replacement by placing a metal frame made of stainless steel in the middle of the wok. Some modern home microwave ovens include the structure to cook food by steam vapor produced in a separate water container, providing a similar result to being cooked by fire.

Overcooking or burning food is easily avoided when steaming it. Health conscious individuals may prefer steaming to other methods which require cooking oil, resulting in lower fat content. Steaming also results in a more nutritious food than boiling because fewer nutrients are leached away into the water, which is usually discarded. A 2007 USDA comparison between steaming and boiling vegetables shows the most affected nutrients are folic acid and vitamin C. When compared to raw consumption, steaming reduces folic acid by 15%, and boiling reduces it by 35%. Steaming reduces vitamin C by 15%, and boiling reduces it by 25%. Phenolic compounds with antioxidant properties have been found to retain significantly better through steaming than through boiling or microwaving. Most other nutrients are reduced by a similar amount by both methods of cooking.

In Western cooking, steaming is most often used to cook vegetables - it is rarely used to cook meats. In Chinese cuisine, vegetables are mostly stir fried or blanched and seldom steamed. Seafood and meat dishes are steamed. For example: steamed whole fish, steamed crab, steamed pork spare ribs, steamed ground pork or beef, steamed chicken, steamed goose, etc. Other than meat dishes, rice can be steamed too, although in Chinese this is rarely referred to as “steaming” but rather simply as “cooking.” Wheat foods are steamed as well. Examples include buns, Chinese steamed cakes, etc. Steamed meat dishes (except fish and some dim sum) are less common in Chinese restaurants than in traditional home cooking because meats usually require longer cooking times to steam than to stir fry. Commercially sold frozen foods (such as dim sum) used to have instructions to reheat by steaming, until the rise in popularity of home microwave ovens which have considerably shorter cooking times.

Smoking is the process of flavoring, cooking, or preserving food by exposing it to the smoke from burning or smoldering plant materials, most often wood. Meats and fish are the most common smoked foods, though cheeses, vegetables, and ingredients used to make beverages such as whisky, Rauchbier and lapsang souchong tea are also smoked.

In Europe, alder is the traditional smoking wood, but oak is more often used now, and beech to a lesser extent. In North America, hickory, mesquite, oak, pecan, alder, maple, and fruit-tree woods, such as apple, cherry and plum, are commonly used for smoking. Other fuels besides wood can also be employed, sometimes with the addition of flavoring ingredients. Chinese tea-smoking uses a mixture of uncooked rice, sugar, and tea, heated at the base of a wok. Some North American ham and bacon makers smoke their products over burning corncobs. Peat is burned to dry and smoke the barley malt used to make whisky and some beers. In New Zealand, sawdust from the native manuka (tea tree) is commonly used for hot smoking fish. In Iceland, dried sheep dung is used to cold smoke fish, lamb, mutton and whale.

Historically, farms in the Western world included a small building termed the smokehouse, where meats could be smoked and stored. This was generally well-separated from other buildings both because of the fire danger and because of the smoke emanations.

Cold smoking can be used as a flavor enhancer for items such as chicken breasts, beef, pork chops, salmon, scallops, and steak. The item can be cold smoked for just long enough to give some flavor. Some cold smoked foods are baked, grilled, roasted, or sautйed before eating. Smokehouse temperatures for cold smoking are below 100 °F (38 °C). In this temperature range, foods take on a smoked flavor, but remain relatively moist. Cold smoking does not cook foods.

Hot smoking exposes the foods to smoke and heat in a controlled environment. Although foods that have been hot smoked are often reheated or cooked, they are typically safe to eat without further cooking. Hams and ham hocks are fully cooked once they are properly smoked. Hot smoking occurs within the range of 165 °F (74 °C) to 185 °F (85 °C). Within this temperature range, foods are fully cooked, moist, and flavorful. If the smoker is allowed to get hotter than 185 °F (85 °C), the foods will shrink excessively, buckle, or even split. Smoking at high temperatures also reduces yield, as both moisture and fat are “cooked” away.

Smoke roasting or smoke baking refers to any process that has the attributes of smoking combined with either roasting or baking. This smoking method is sometimes referred to as “barbecuing”, “pit baking”, or “pit roasting”. It may be done in a smoke roaster, closed wood-fired masonry oven or barbecue pit, any smoker that can reach above 250 °F (121 °C), or in a conventional oven by placing a pan filled with hardwood chips on the floor of the oven so the chips smolder and produce a smokebath. However, this should only be done in a well-ventilated area to prevent carbon monoxide poisoning.
