The British thermal unit is a measure of heat, which is a form of energy. It was originally defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. The SI unit for energy is the joule (J); one BTU equals about 1,055 J.
A wok is a deep round-bottomed cooking pan of Chinese origin. It is believed to be derived from the South Asian karahi. It is common in Greater China, and similar pans are found in parts of East, South and Southeast Asia, as well as being popular in other parts of the world.
Barbecue or barbeque is a term used with significant regional and national variations to describe various cooking methods that employ live fire and smoke to cook the food. The term is also generally applied to the devices associated with those methods, the broader cuisines that these methods produce, and the meals or gatherings at which this style of food is cooked and served. The cooking methods associated with barbecuing vary significantly but most involve outdoor cooking.
Grilling is a form of cooking that involves heat applied to the surface of food, commonly from above, below or from the side. Grilling usually involves a significant amount of direct, radiant heat, and tends to be used for cooking meat and vegetables quickly. Food to be grilled is cooked on a grill, using a cast iron/frying pan, or a grill pan.
Smoking is the process of flavoring, browning, cooking, or preserving food by exposing it to smoke from burning or smoldering material, most often wood. Meat, fish, and lapsang souchong tea are often smoked.
Outdoor cooking is the preparation of food in the outdoors. A significant body of techniques and specialized equipment exists for it, traditionally associated with nomadic cultures such as the Berbers of North Africa, the Arab Bedouins, the Plains Indians, pioneers in North America, and indigenous tribes in South America. These methods have been refined in modern times for use during recreational outdoors pursuits, by campers and backpackers.
A barbecue grill or barbeque grill is a device that cooks food by applying heat from below. There are several varieties of grills, with most falling into one of three categories: gas-fueled, charcoal, or electric. There is debate over which method yields superior results.
A stove or range is a device that generates heat inside or on top of the device, for local heating or cooking. Stoves can be powered with many fuels, such as electricity, natural gas, gasoline, wood, and coal.
A deep fryer is a kitchen appliance used for deep frying. Deep frying is a method of cooking by submerging food into oil at high heat, typically between temperatures of 350 to 375 °F.
Induction cooking is performed using direct electrical induction heating of cooking vessels, rather than relying on indirect radiation, convection, or thermal conduction. Induction cooking allows high power and very rapid increases in temperature to be achieved: changes in heat settings are instantaneous.
Indirect grilling is a barbecue cooking technique in which the food is placed to the side of or above the heat source instead of directly over the flame as is more common. This can be achieved by igniting only some burners on a gas barbecue or by piling coals to one side of a charcoal pit. A drip tray is placed below the food to prevent fat from the food igniting and generating a direct flame. Indirect grilling is designed to cook larger or tougher foods that would burn if cooked using a direct flame. This method of cooking generates a more moderate temperature and allows for an easier introduction of wood smoke for flavoring.
Barbecue varies by the type of meat, sauce, rub, or other flavorings used, the point in barbecuing at which they are added, the role smoke plays, the equipment and fuel used, cooking temperature, and cooking time.
The following outline is provided as an overview of and topical guide to food preparation:
Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods.
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the emitter and cool object is needed for the energy transfer. Infrared heaters can be operated in vacuum or atmosphere.
A kamado is a traditional Japanese wood- or charcoal-fueled cook stove.
A flattop grill is a cooking appliance that resembles a griddle but performs differently because the heating element is circular rather than straight. This heating technology creates an extremely hot and even cooking surface, as heat spreads in a radial fashion over the surface. Flattop grills have been around for hundreds of years in various forms and evolved in a number of cultures.
Charcoal is a lightweight black carbon residue produced by strongly heating wood in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettes used for outdoor cooking may contain many other additives, e.g. coal.
