Boiling and blanching
Boiling
Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. Th ...
water has a recovery time which occurs when food is added to it, particularly large amounts of food. Methods to reduce recovery time are to use a larger quantity of water, cooking a lesser amount of food at a time, and using a stronger heat source. Industrial and restaurant blanching equipment is susceptible to a recovery time, in which the blanching liquor requires time to reheat to its preset cooking temperature.
Deep fryer
Deep fryers have a recovery time after food is cooked in them. A faster recovery time shortens the cooking time, which lessens the amount of oil absorbed into the deep fried foods. This results in a superior product compared to deep fried foods that are highly saturated with oil, and also reduces the amount of oil needed to be re-added to the deep fryer. The use of a 1:6 ratio of food content relative to oil content has been demonstrated to minimize recovery time in deep fryers.Oven

A baking stone is a portable cooking surface used in baking. It may be made of ceramic, stone or, more recently, salt. Food is put on the stone, which is then placed in an oven, though sometimes the stone is heated first. Baking stones are used m ...
