orange peel: you can use just zest
Orange peel is rich in vitamin C, fiber, and polyphenols with antioxidant properties; the white pith (albedo) is particularly high in pectin, a soluble fiber beneficial for digestive health.
About
Orange peel is the outer colored skin and underlying white pith of Citrus × sinensis, a hybrid citrus fruit native to Southeast Asia and now cultivated globally. The peel contains two distinct layers: the colored exterior (flavedo) rich in aromatic oils and essential oils like limonene, and the bitter white spongy tissue beneath (albedo) that provides natural pectin. The zest—the colored outer layer only—is prized for its concentrated citrus oils and bright, volatile aromatics, while the whole peel includes both layers and carries more bitterness.
Culinary Uses
Orange peel is used in both sweet and savory applications. Zest (the colored outer layer without pith) adds bright citrus flavor to baked goods, desserts, marinades, sauces, and cocktails without introducing bitterness. The whole peel, including the white pith, is candied as a confection, brewed as tea, and used in traditional medicine infusions. It also features in spice blends, marmalade production, and as a garnish. The volatile oils make zest best added near the end of cooking to preserve aromatic qualities, while candied peel sustains longer cooking.
