Zesting is the process of removing the colored outer layer of citrus fruit peel, which contains flavorful oils. You can zest lemons, limes, oranges, grapefruits, and other citrus fruits.
Zesting involves scraping or grating the outer, colored part of the citrus peel, known as the zest. This layer is rich in essential oils that impart a concentrated citrus flavor and aroma to dishes. It's important to avoid the white pith underneath the zest, as it's bitter and can negatively affect the taste.
Here's a breakdown of common citrus fruits that are zested:
* **Lemons:** Provide a bright, acidic flavor.* **Limes:** Offer a tart, slightly sweet flavor.* **Oranges:** Contribute a sweet, aromatic flavor.* **Grapefruits:** Impart a bittersweet, tangy flavor.* **Mandarins/Tangerines:** Similar to oranges, but often sweeter and more floral.* **Citrons:** Have a thick rind and a mild, floral flavor.
To zest a citrus fruit effectively, use a zester, microplane, or fine grater. Gently run the tool over the fruit's surface, applying light pressure to remove only the colored zest. Rotate the fruit as you go to avoid grating the bitter white pith.
Before zesting, thoroughly wash and dry the citrus fruit to remove any dirt, wax, or pesticides from the peel. Consider using organic citrus fruits to minimize exposure to chemicals.
