peel of 1 orange

Orange peel, the outer skin (flavedo) and white pith (albedo) of the orange fruit (Citrus × sinensis), is a byproduct of consuming fresh oranges that has significant culinary and medicinal value. The flavedo contains numerous essential oil glands that produce the characteristic volatile compounds responsible for orange's bright, citrusy aroma, while the white pith beneath contains pectin and additional flavonoids. Orange peel can be used fresh, dried, or candied, and varies in thickness and oil content depending on the orange variety and growing conditions. Sweet orange varieties such as Valencia and Navel oranges produce milder, more pleasant peels than bitter or Seville oranges, which have more pronounced and astringent characteristics.

Orange peel is used across multiple culinary traditions to add bright citrus flavor and aromatic complexity to both sweet and savory dishes. Fresh peel is zested (finely grated) to garnish desserts, cocktails, and fish dishes, while dried peel appears in spice blends, broths, and herbal teas. Candied orange peel serves as a confection and ingredient in chocolate coating and baking. In Asian cuisines, dried orange peel (陈皮, chen pi) is a key component in braises and stews, lending depth and subtle bitterness. The peel also features in marmalades, infused spirits, and as a flavoring agent in cured meats and sausages.
