Steaming is a method ofcooking usingsteam. This is often done with afood steamer, a kitchen appliance made specifically to cook food with steam, but food can also be steamed in awok. In the American Southwest, steam pits used for cooking have been found dating back about 5,000 years. Steaming is considered a healthy cooking technique that can be used for many kinds of foods.
Compared to full immersion inboiling water, steaming can be faster and more energy-efficient because it requires less water and takes advantage of the excellent thermodynamic heat transfer properties of steam.
Some of the world's earliest examples of steam cooking were found in China'sYellow River Valley; early steam cookers made ofstoneware have been found dating back as far as 5,000BCE.[1] And also inGunma Prefecture,Japan, created during theStone Age.[2][3] Some of the earliest examples of steam cooking have been found inItaly andSardinia, created during theBronze Age,[4] and inCochise County, Arizona, where steam pits were used for cooking about 10,000 years ago.[5] From the eighth centuryCE,[citation needed] thin cypress strips were used to make steamers; today, their slatted bases are constructed frombamboo. The classic steamer has a chimney in the center, which distributes the steam among the tiers.[citation needed]
While steaming has not caught up in the west for assorted dishes, the technique has been heavily popularized worldwide by Chinese and East Asian cuisine.[6] The two main classic steamers feature the ancientbamboo steamer as well as the modern metal (aluminium or stainless steel) steamer, with the difference being that the bamboo lid takes longer to heat up but absorbs excess moisture and allows heat to condense again over the delicate food.[7] Other developments were the creation of microwaveable silicone steamers and plastic-hybrid steamers.[7]
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 fromdouble boiling, in which food is not directly exposed to steam, orpressure cooking, which uses a sealed vessel but is capable of pressure steaming or submerging.[citation needed]
Such cooking is most often done by placing the food in a food steamer, typically a circular container made of metal, wood, or bamboo. The steamer usually has a lid that is placed on top of the container during cooking to allow the steam to cook through the food. When a steamer is unavailable, food can be steamed inside a wok, supported over boiling water in the bottom of the wok by a metal frame. Some modern homemicrowave ovens include a structure to cook food with steam vapor produced in a separate water container, providing a similar result to being cooked on a stove. There are also specialized steam ovens available.[citation needed]
In Japan, glutinous rice is steamed to preparemochi rice cakes. Traditional Japanese sweets orwagashi making involves steaming rice or wheat dough for making mochigashi and manju.[citation needed]
In Western cooking, steaming is most often used to cook vegetables—it is rarely used to cook meats. However,steamed clams are prepared by steaming. WithChinese cuisine, vegetables are usuallystir fried orblanched and seldom steamed. Seafood and meat dishes are steamed. For example: Steamed wholefish, steamedcrab, steamed pork spare ribs, steamedgroundpork orbeef, steamedchicken and steamedgoose.[citation needed]
Rice can be steamed too, although in Chinese cooking this is simply referred to as "cooking" rather than "steaming". In Thailand steaming is the definition of minimalist cooking.[8]Wheat foods are steamed as well. Examples includebuns and Chinese steamed cakes. Similarly, inMexican andCentral American cuisine,tamales are made by steaming a dough made fromnixtamalizedmaize (calledmasa) in wrappers made from corn husks or banana leaves; the dough can be stuffed or left plain.[citation needed]
Steamed meat dishes (except fish and somedim sum) are less common in Chinese restaurants than in traditional home cooking,[9] because meats usually require longer cooking times to steam than to stir fry. Commercially soldfrozen foods (such as dim sum) formerly had instructions to reheat by steaming, until the rise in popularity of home microwave ovens, which have considerably shorter cooking times.[citation needed]

Sweets: steaming is an important process in Japanese sweets making such asmanjū,yōkan,uirō,karukan orsuama.
Overcooking or burning food is easily avoided when steaming it. Individuals preferring to avoid additional fat intake may prefer steaming to methods which require cooking oil.[citation needed]
A 2007USDA comparison between steaming and boiling vegetables shows the most affected nutrients arefolic acid andvitamin 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%.[14]
Steaming, compared to boiling, showed 42% higher amount ofglucosinolates in broccoli cooked for medium firmness.[15]Phenolic compounds with antioxidant properties have been found to retain significantly better through steaming than through boiling or microwaving.[16] Steaming compared to boiling retainedβ-carotene in carrots.[17] The effect of cooking food may increase or decrease the nutrients.[14][18]
