Lemon zest is the outer, colorful layer of a lemon's peel, prized for its intense citrus aroma and flavor. You can get it directly from fresh lemons, or sometimes pre-packaged.
What is Lemon Zest?
Lemon zest is specifically the outer, yellow part of the lemon peel. This layer contains the lemon's essential oils, which hold the majority of its distinctive citrus flavor and fragrance. It's important to avoid including the white pith underneath, as it's bitter and can negatively affect the taste of your dish. Think of it as capturing the soul of the lemon!
Where Can You Get Lemon Zest?
You have two primary options for obtaining lemon zest:
-
From Fresh Lemons: This is the most common and preferred method.
- Purchase fresh lemons: Look for lemons that are firm, have vibrant yellow color, and are free from blemishes. Organic lemons are recommended if you plan to use the zest, to avoid potential pesticide residue.
- Zest the lemon: Use a tool like a microplane, zester, grater, or even a vegetable peeler. Microplanes are popular because they create a fine zest, releasing more of the lemon's oils. A vegetable peeler can be used to remove wider strips, which can then be finely chopped. Be sure to only remove the outer, yellow layer.
- Use Immediately or Store: Lemon zest is best used immediately for maximum flavor. However, it can be stored in an airtight container in the refrigerator for a few days, or frozen for longer preservation.
-
Pre-packaged: Although less common, you might find dried or frozen lemon zest in the spice aisle of some supermarkets. However, be aware that pre-packaged zest may not have the same intense flavor as freshly grated zest.
In summary, lemon zest is the flavorful outer peel of a lemon, best obtained fresh but sometimes available pre-packaged. Freshly zested lemon will provide the best flavor profile for your recipes.
