Orange Zest

Orange zest is the finely grated colored outer peel of an orange. It releases aromatic citrus oils with a vivid spray and tastes bright with a mild bitter edge; avoid the white pith for cleaner flavor. Use it to flavor baked goods, vinaigrettes, marinades, syrups, and cocktails, applied fresh as fine gratings or in thin strips.\n\nCitrus originated in Southeast Asia, and sweet oranges spread through China to the Mediterranean via trade; cooks in Europe, North Africa, and the Middle East popularized zest in pastries, sauces, and spice blends. Dried orange peel appears in baking and confectionery as well as infusions, while fresh zest is taken from market oranges grown in subtropical regions.
