Preserving food by salting is a method of curing that has been used for centuries. Curing is the process of preserving food by adding salt, sugar, nitrates, or nitrites to the food. The salt helps to draw out moisture from the food, which prevents the growth of bacteria and other microorganisms. The sugar helps to create an environment that is inhospitable to bacteria, while the nitrates and nitrites help to prevent the growth of botulism. Curing with salt is a great way to preserve food for long periods of time, and the term for this process is 'CURE' (4 letters).
