My sister and I recently spent some time together in Florida and of course enjoyed some Key Lime Pie. We were curious to learn more about key limes and what other uses there might be for them besides the delicious pie.
Key Limes are also known as Mexican or West Indies limes. They are smaller and sweeter than Persian limes (the kind you typically find in the grocery store) and have more seeds. They have a high juice content and thin, leathery skin. When purchasing key limes, choose those that are heavy for their size, firm, shiny, and have no blemishes or bruises.
Today most key limes come from Mexico and are available year round. The green color indicates they are immature but the juice from green key limes is known for it’s tart flavor. As key limes ripen they become more of a yellow color and their flesh is less acidic leading to a sweeter flavor.
Key limes can be stored in the pantry for up to one week. For longer storage you can keep them in a plastic bag in the refrigerator for 3 to 4 weeks. You can also freeze key limes whole. For best quality use frozen key limes within 3 to 4 months. You can defrost them in the microwave for a few seconds or in water for @15 minutes. They will be mushy when thawed but will be great for the juice.
Besides the pie, key limes can be used in cookies, cupcakes, cocktails, marinades and dressings. We have been inspired to experiment using key limes and reminicising about our fun times in Florida!
