Zest
Description
Zest refers to the outermost layer of citrus fruits such as lemons, limes, oranges, and grapefruits. It is rich in oils and provides a strong, tangy flavor that can enhance a multitude of dishes. It is carefully grated from the fruit, avoiding the bitter white pith underneath, and can be used in both sweet and savory recipes. Zest is measured in both teaspoons (tsp) and tablespoons (tbsp) in American recipes, while European recipes often use grams (g) or milliliters (ml) when it's called for in liquid zest extracts.
