What is the best way to extract key lime juice for storage?
When it comes to extracting key lime juice, it is essential to use a method that minimizes waste and preserves the flavor and aroma of the limes. One of the most effective ways to extract key lime juice is by using a manual or electric juicer. These devices allow you to extract the juice from the limes without introducing heat, which can damage the delicate flavor and aroma compounds. Simply cut the limes in half, extract the juice using your chosen method, and strain the juice to remove any seeds or pulp.
For those who do not have access to a juicer, squeezing the limes by hand is also a viable option. To do this, cut the limes in half and use a cheesecloth or fine-mesh sieve to squeeze out the juice. This method may be more time-consuming and labor-intensive, but it can be just as effective as using a juicer. Regardless of the method you choose, it is crucial to extract the juice in a way that minimizes exposure to heat, light, and oxygen, as these factors can cause the juice to degrade and lose its flavor and aroma.
