Pickled foods are items that have been preserved in a solution of vinegar, salt, or brine. This process not only extends their shelf life but also enhances their flavor. Common examples of pickled foods include cucumbers, onions, and cabbage, which are often enjoyed as side dishes or condiments. The pickling process involves immersing the food in the preserving solution, allowing it to ferment over time. This fermentation can create beneficial probiotics, which are good for gut health. Pickled foods are popular in many cultures and can be found in various cuisines around the world, adding a tangy taste to meals.
