Expiration & Storage Tips
When does key lime expire?
Key limes are usually best used within 2 weeks of purchase when stored at room temperature, but if you want to extend their life, you can refrigerate them where they can last for around a month. If you have a lot of limes and can't use them within this timeframe, juicing the limes and freezing the juice will allow it to last for 3 to 4 months in the freezer.
How do you tell if key lime is bad?
The easiest way to tell if a key lime has gone bad is by looking at its color and feel. If the exterior has turned a light brown and the skin has softened, it may still be edible but the flavor will have started to deteriorate. If the limes have shriveled, feel dry or if there is any visible mold, discard the limes as they are likely spoiling. Similarly, if the juice has been frozen for more than 5 months, it is likely to start losing its flavor and fresh aroma.
Tips for storing key lime to extend shelf life
• Store key limes at room temperature if you plan to use them within a week or two.
• For a longer shelf life, keep them in the refrigerator, inside a plastic bag in the crisper drawer to conserve moisture.
• If you have a large quantity of key limes, consider squeezing and freezing the juice in ice cube trays. Once frozen, transfer these 'lime cubes' to a freezer bag or airtight container. You'll have fresh lime juice ready to use for months.
• Avoid keeping limes in a bowl of fruits where they can ripen quickly due to ethylene gas released by other fruits.
• Limes are sensitive to damage so handle them with care to avoid bruising or breaking the skin, which can cause them to deteriorate faster.
