Question

Don't let your leftover zest go to waste. Discover creative and delicious ways to use it, from making flavored sugars to beautiful garnishes.

Answer 1

Leftover zest can be used to infuse sugar or salt for a flavorful seasoning, or dried and added to homemade spice blends. It also makes a vibrant addition to vinaigrettes and marinades.

Detailed Explanation:

When you've zested a lemon, lime, orange, or grapefruit, don't throw away that flavorful peel! There are numerous creative ways to use it. Here's a breakdown:

1. Citrus Sugar/Salt: Combine the zest with granulated sugar or coarse salt in a jar. Use your fingers to rub the zest into the sugar/salt, releasing its oils. Seal the jar and let it sit for at least a few days, shaking occasionally. The sugar or salt will absorb the citrus flavor and aroma. This is fantastic for baking, rimming cocktail glasses, or adding a special touch to savory dishes.
2. Spice Blends: Dry the zest by spreading it on a baking sheet at a low temperature (around 170°F or 77°C) for about an hour, or until completely dry. Once dry, you can grind it into a powder and add it to homemade spice blends for rubs, seasonings, or even tea blends.
3. Infused Oils: Add citrus zest to olive oil or other cooking oils to create a flavorful infused oil. Gently heat the oil with the zest for a short period (avoid boiling), then let it cool and steep for a few days before straining out the zest. This oil is excellent for drizzling over salads, pasta, or grilled vegetables.
4. Vinaigrettes and Marinades: Fresh or dried zest can be added directly to vinaigrettes and marinades to brighten the flavor profile. The citrus oils will emulsify with the other ingredients, adding a zesty kick to your dishes.
5. Citrus Dust: Dehydrate the zest until brittle, then grind it into a fine powder. This 'citrus dust' can be used as a garnish for desserts, cocktails, or even savory dishes, adding a concentrated burst of citrus flavor.

Pro Tip:

To maximize the flavor of your zest, use a microplane zester. It removes only the outer layer of the peel, avoiding the bitter white pith underneath. Store leftover zest in an airtight container in the refrigerator for up to a week, or freeze it for longer storage.
