Preserved lemons are a traditional ingredient in North African and Middle Eastern cuisine. They are lemons that have been pickled in salt and their own juice, giving them a tangy, salty, and slightly sour flavor. The process of preserving lemons softens the flesh and intensifies the lemony flavor. Preserved lemons can be used in a variety of dishes, such as tagines, salads, roasted meats, and dips. They are also a popular ingredient in Mediterranean and Moroccan cuisine.
