Lemon Zest
Description
Lemon zest is the colorful outer layer of the lemon peel, often used to add a bright, citrusy flavor to a variety of recipes. It contains the fruit's essential oils, which are responsible for that fresh, tangy aroma and taste. When a recipe calls for lemon zest, it typically involves grating the outermost skin of the lemon, taking care not to include the white pith underneath, which can be bitter. In terms of measurements, lemon zest is commonly used in small quantities, such as teaspoons (tsp) or tablespoons (tbsp), which correspond to approximately 5 milliliters (ml) or 15 milliliters (ml) respectively in American and European units. Alternatively, it can also be measured in grams (g) or ounces (oz) depending on the recipe.
Common uses
Lemon zest is used in a wide array of culinary preparations, from sweet to savory. It's often used as a garnish, added to marinades, dressings, sauces, baked goods, desserts, and cocktails. It is also a key flavoring in many spice blends and herbal teas.
