<P> Boiling can be done in several ways: The food can be placed into already rapidly boiling water and left to cook, the heat can be turned down and the food can be simmered or the food can also be placed into the pot, and cold water may be added to the pot . This may then be boiled until the food is satisfactory . </P> <P> Water on the outside of a pot, i.e., a wet pot, increases the time it takes the pot of water to boil . The pot will heat at a normal rate once all excess water on the outside of the pot evaporates . </P> <P> Boiling is also often used to remove salt from certain foodstuffs, such as bacon if a less saline product is required . </P> <P> Also known as "boil - in - bag", this involves heating or cooking ready - made foods sealed in a thick plastic bag . The bag containing the food, often frozen, is submerged in boiling water for a prescribed time . The resulting dishes can be prepared with greater convenience as no pots or pans are dirtied in the process . Such meals are available for camping as well as home dining . </P>
