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.
Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs on the surface. Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure ...
This process is used industrially to make such food products as evaporated milk for milk chocolate and tomato paste for ketchup. Vacuum evaporation plant vacuum pans in a beet sugar factory. In the sugar industry vacuum evaporation is used in the crystallization of sucrose solutions. Traditionally this process was performed in batch mode, but ...
Liquids are so important to cooking that the name of the cooking method used is often based on how the liquid is combined with the food, as in steaming, simmering, boiling, braising and blanching. Heating liquid in an open container results in rapidly increased evaporation , which concentrates the remaining flavor and ingredients; this is a ...
In cooking, reduction is the process of thickening and intensifying the flavor of a liquid mixture, such as a soup, sauce, wine or juice, by simmering or boiling. [1] Reduction is performed by simmering or boiling a liquid, such as a stock, fruit or vegetable juice, wine, vinegar or sauce, until the desired concentration is reached by ...
Once it’s boiling, reduce the heat to a smaller boil so it doesn’t overflow. Cook until you can pierce the potatoes with a fork and it easily slides in (around 20 minutes).

Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when ...
