Salt curing is a preservation method that uses salt to draw moisture out of food, inhibiting the growth of bacteria and mold. This technique is commonly applied to meats and fish, allowing them to be stored for longer periods without refrigeration. The salt creates a dry environment that helps maintain the food's flavor and texture. The process involves covering the food with salt or soaking it in a salt brine. Over time, the salt penetrates the food, enhancing its taste while preserving it. Salt curing has been used for centuries and remains popular in various cuisines around the world.
