The Food Prep Mistake That Ruins Citrus Zest Flavor

As many home cooks already know, zesting citrus can add bright flavor to many dishes — sweet and savory alike. When a recipe calls for a lot of grated citrus peel, it may be tempting to prep it all in advance, but this is a big mistake.

Citrus zest, particularly that of lemons, is known for its potent flavor and aromatic oils. The zest contains a concentrated amount of these oils, which contribute to its vibrant taste and fragrance. However, when the peel of the citrus fruit is grated too far ahead of time, one key issue that impacts quality and flavor of the zest can arise.

The same aromatic oils that make citrus zest so desirable are volatile substances that evaporate very quickly when exposed to air. So when you pull out and use the microplane well before you actually need the zest, the oils in the small, fragrant pieces of peel have far more time to dissipate, leaving you with underwhelming, dried-out zest. Instead, consider cutting down on time by prepping other steps within the recipe.

How to maximize citrus zest

Make the most of citrus zest and ensure it retains its flavorful qualities by following a few tips. Apart from waiting to grate the fruit until you are ready to use it, you can also zest citrus more carefully. Aim to only get the colorful outer skin, avoiding the white pith underneath. This inner layer can impart an undesirable bitterness.

Using fresh citrus is another way to get the most fragrance out of your zest, so it is important to extend the shelf life for as long as possible. Citrus fruits stored at room temperature generally last for up to one week. But if they are very ripe or if you do not plan to use them right away, it might be necessary to refrigerate them. Place the fruits in an airtight bag and store them in the fridge for up to one month to increase its lifespan.

So, embrace the freshness factor and zest your fruit at the right moment to elevate your culinary creations with the tantalizing taste and aroma of citrus.
