Preserved lemons are whole lemons that have been cured in salt and their own juices. This process enhances their flavor, making them tangy and slightly sweet. They are commonly used in Mediterranean and North African cuisines, adding depth to various dishes. To make preserved lemons, lemons are cut and packed with salt in a jar, allowing them to ferment over several weeks. The result is a soft, flavorful ingredient that can be used in salads, stews, and marinades. They are often included in recipes for tagines and other savory meals, providing a unique taste.
