Lemon zest is commonly used in both sweet and savory dishes for its bright, tangy flavor, making it ideal for desserts, dressings, and marinades. Orange zest, with its sweeter and more aromatic profile, is often used in baked goods, cocktails, and sauces. Lemon pith, the bitter white layer under the zest, is usually avoided in cooking but can be used in small amounts for flavoring stocks. Orange pith is similarly bitter and generally discarded, though it can be used in marmalades or infusions where a deeper flavor is desired.
