Traditionally a way of preserving vegetables to extend their shelf life as well as add flavour before the days of refrigeration, most cultures have their own version of pickled and fermented foods. What’s most interesting is that they are currently experiencing a revival in popularity, partly due to a renaissance in the back-to-basics approach in the kitchen but also because of their numerous health benefits, particularly supporting the immune system and aiding digestion.
Fermented foods such as the Wild Sauerkraut, below, are made by adding salt to vegetables to stop them going off, while leaving them at room temperature to allow the natural bacteria and wild yeasts found in the environment and the cabbage leaves to preserve them. This results in the vegetables developing a softer texture and a mildly acidic flavour. Pickles on the other hand rely on a combination of salt and vinegar as a preservative and tend to have a more piquant flavour.
