This technique uses a thin layer of heated oil to coat the pan. The oil layer is the method of heat transfer between the burner and the food. Water vapor is a critical component of how pan frying works. Raw meat products contain up to 73% water. [4] The meat is cooked by the evaporation of this water.
Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
Boiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. [13] Simmering is gentle boiling, while in poaching the cooking liquid moves but scarcely bubbles. [14] The boiling point of water is typically considered to be 100 °C (212 °F; 373 K), especially at sea level.
The vacuum evaporation treatment process consists of reducing the interior pressure of the evaporation chamber below atmospheric pressure. This reduces the boiling point of the liquid to be evaporated, thereby reducing or eliminating the need for heat in both the boiling and condensation processes.

Vegetables being sweated, showing a lack of browning. Sweating in cooking is the gentle heating of vegetables in a little oil or butter, with frequent stirring and turning to ensure that any emitted liquid will evaporate. [1] Sweating usually results in tender, sometimes translucent, pieces. [2]

Pressure cookers produce superheated water, which cooks the food more rapidly than boiling water. Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F). [citation needed] It is also known as "subcritical water" or "pressurized hot water".
