Lemons are bright, tart citrus fruits prized for their acidic juice, aromatic zest, and vibrant flavor. Commonly used to flavor drinks, dressings, marinades, baked goods, and savory dishes, they add acidity and balance. Store lemons in the refrigerator to extend shelf life; roll before juicing to maximize juice yield. Ideal as garnish or in homemade cleaners for culinary and household uses.
