What is "zest"?

Zest refers to the outermost layer of the peel of citrus fruits, such as lemons, oranges, and limes. It is characterized by its bright color and intense, aromatic flavor. Zest contains flavorful essential oils and aromatic compounds that add a burst of citrusy flavor to dishes. It is commonly used as a flavoring agent in cooking and baking, imparting a tangy and refreshing taste to a wide variety of recipes, including desserts, sauces, marinades, and beverages. Zest can be obtained by grating or scraping the outer surface of the fruit's peel using a grater, zester, or citrus peeler. It adds both flavor and visual appeal to dishes, enhancing their overall taste and presentation.
