The basic principles of salting involve the use of salt to preserve food by inhibiting the growth of bacteria and mold. Salt draws moisture out of food through osmosis, creating an environment that is less hospitable to microorganisms. Additionally, it enhances flavor and can improve texture. Salting can be done through dry methods, where salt is applied directly, or wet methods, where food is submerged in a brine solution.
