Orange Zest

Orange zest is the colorful outer layer of the peel of an orange, rich in oils and aromatic compounds. It is a versatile ingredient that can be used fresh, dried, or candied, and is particularly popular in baking. Orange zest is available year-round, as oranges are cultivated in various regions globally, allowing for continuous harvests. It is a key flavoring in Mediterranean, Middle Eastern, and Asian cuisines, often found in desserts, marinades, and spice blends. The zest adds a bright, citrusy note to dishes without the acidity or liquid content of orange juice.

Different Forms/Types of Orange Zest

Dried zest

Dehydrated orange zest, which can be used as a convenient substitute when fresh zest is not available.

Fresh zest

The outermost layer of the orange peel, grated or finely shredded, used to add a burst of citrus flavor and aroma.

Candied zest

Orange zest that has been blanched and then simmered in sugar syrup, resulting in a sweetened, chewy product often used in baking and confections.

How to Choose Orange Zest

When selecting oranges for fresh zest, choose ones that are heavy for their size, indicating juiciness, and have a brightly colored, unblemished rind. Organic oranges are often recommended for zesting to avoid pesticide residues. For dried zest, look for products with a vibrant color and a strong citrus aroma, which indicates freshness.

Cooking/Prep Tips for Orange Zest

Orange zest offers a burst of citrus flavor and aromatic oils that can brighten up a variety of dishes. For intermediate and expert home cooks, it's important to use only the colored part of the peel, avoiding the bitter white pith beneath. A microplane grater is ideal for creating fine zest, but a traditional zester or the fine side of a box grater can also be used. When using orange zest, add it towards the end of cooking to preserve its delicate flavor, or use it as a garnish. For cold dishes or baking, it can be mixed in with other ingredients. Since orange zest is potent, start with a small amount and adjust to taste.

Shelf Life of Orange Zest

Fresh orange zest should be used immediately for the best flavor, but it can be stored in an airtight container in the refrigerator for a couple of days. Dried zest should be kept in a cool, dark place in a tightly sealed container to maintain its potency. Candied zest can be stored in an airtight container at room temperature, away from moisture and heat.
