Key limes, with their bright green color and tart flavor, are a staple in many recipes, from classic key lime pie to refreshing summer cocktails. However, their small size and high water content make them prone to spoilage, leaving many of us wondering how to make them last longer. The good news is that with a few simple tips and tricks, you can extend the shelf life of your key limes and enjoy their flavor and aroma for a longer period.
Choosing the Right Key Limes
Before we dive into the tips on how to make key limes last longer, it’s essential to choose the right ones in the first place. When selecting key limes, look for those that are:
- Firm and heavy for their size
- Bright green in color with no signs of yellowing or browning
- Have a slight give when pressed, but still retain some firmness
- Free of bruises, soft spots, or mold
Avoid key limes that are:
- Soft, mushy, or wrinkled
- Overripe or showing signs of decay
- Discolored or have white spots
Storing Key Limes at Room Temperature
Once you have chosen the right key limes, it’s essential to store them properly to extend their shelf life. One way to store key limes is at room temperature. This method is ideal for short-term storage, typically up to a week. To store key limes at room temperature:
- Place them in a breathable container, such as a paper bag or a mesh bag, to prevent moisture buildup
- Keep them away from direct sunlight, heat sources, and strong-smelling foods
- Check on them regularly to remove any that are spoiling, as this can affect the rest
Refrigerating Key Limes
Refrigerating key limes is another excellent way to extend their shelf life. This method can keep them fresh for up to three weeks. To refrigerate key limes:
- Place them in a breathable container or wrap them individually in plastic wrap or aluminum foil
- Store them in the refrigerator at a consistent temperature below 40°F (4°C)
- Check on them regularly to remove any that are spoiling
Freezing Key Limes
Freezing key limes is an excellent way to preserve them for an extended period. Frozen key limes can be stored for up to six months. To freeze key limes:
- Wash and dry them thoroughly to prevent moisture buildup
- Place them in an airtight container or freezer bag, making sure to remove as much air as possible
- Store them in the freezer at 0°F (-18°C) or below
- When ready to use, simply thaw the desired amount at room temperature or use them directly in your recipe
Juicing and Freezing Key Lime Juice
If you plan to use key lime juice in your recipes, you can juice them and freeze the juice for later use. This method is excellent for making key lime juice last longer and is ideal for recipes that require a large amount of juice. To juice and freeze key lime juice:
- Juice the key limes using a manual or electric juicer
- Strain the juice to remove any pulp or sediment
- Pour the juice into an airtight container or freezer bag, making sure to remove as much air as possible
- Store the juice in the freezer at 0°F (-18°C) or below
- When ready to use, simply thaw the desired amount at room temperature or use it directly in your recipe
Tips for Using Frozen Key Lime Juice
When using frozen key lime juice, keep the following tips in mind:
- Frozen key lime juice is best used within six months for optimal flavor and aroma
- Always thaw frozen key lime juice in the refrigerator or at room temperature to prevent bacterial growth
- Use frozen key lime juice in recipes that require a large amount of juice, such as key lime pie or key lime bars
Other Methods to Make Key Limes Last Longer
In addition to storing, refrigerating, and freezing key limes, there are other methods to extend their shelf life. These methods include:
Pickling Key Limes
Pickling key limes is a great way to preserve them and add a tangy, salty flavor to your recipes. To pickle key limes:
- Slice the key limes thinly and pack them into a clean glass jar
- Cover the key limes with a brine made from vinegar, salt, and water
- Seal the jar and store it in the refrigerator
- Use the pickled key limes in recipes or as a garnish for cocktails
Dehydrating Key Limes
Dehydrating key limes is another method to preserve them and add a concentrated flavor to your recipes. To dehydrate key limes:
- Slice the key limes thinly and place them in a single layer on a dehydrator tray
- Dehydrate the key limes at 135°F (57°C) for 6-8 hours or until they reach the desired level of dryness
- Store the dried key limes in an airtight container
- Use the dried key limes in recipes or rehydrate them by soaking them in water or juice

How do I store key limes to keep them fresh for a longer period?
Store key limes at room temperature, away from direct sunlight and heat sources. This will help to slow down the ripening process. You can also store them in the refrigerator to prolong their shelf life. Make sure to keep them away from strong-smelling foods as key limes can absorb odors easily.
It’s also important to store key limes in a paper bag or wrap them in a paper towel to maintain humidity. This will help to prevent moisture from escaping and keep the skin of the key lime from becoming dry and wrinkled. You can also store key limes in a breathable container, such as a mesh bag or a cloth bag, to maintain airflow and prevent moisture buildup.
How can I use up ripe key limes before they go bad?
Use up ripe key limes by incorporating them into various recipes, such as key lime pie, key lime juice, or key lime marinades for meats and seafood. You can also use them to make marmalades, sauces, and dressings. Ripe key limes are perfect for adding a burst of citrus flavor to cocktails, smoothies, and other beverages.
If you have a surplus of ripe key limes, consider freezing the juice or zest for later use. Simply juice the key limes and pour the juice into an ice cube tray. Once frozen, transfer the cubes to a freezer-safe bag or container for up to 6 months. You can also freeze the grated zest in an airtight container for up to 3 months.
Can I use key lime juice as a substitute for regular lime juice?
Yes, you can use key lime juice as a substitute for regular lime juice in many recipes. However, keep in mind that key lime juice has a more intense, tart flavor than regular lime juice. Start with a small amount and taste as you go, adjusting the amount to your desired level of tartness.
Key lime juice is especially well-suited for recipes that require a strong citrus flavor, such as key lime pie, ceviche, and marinades for seafood. It’s also a great addition to cocktails, adding a unique twist to classic recipes. Just be aware that key lime juice may change the flavor profile of the dish slightly, so it’s best to taste and adjust as needed.
How do I choose the best key limes at the store?
When choosing key limes at the store, look for ones that are heavy for their size and have a bright green color. Avoid key limes that are soft, wrinkled, or have brown spots. Key limes should be firm to the touch and have a slight give when squeezed.
It’s also important to check the stems of the key limes. Fresh key limes will have a tender, green stem that comes off easily. Avoid key limes with dry, brittle stems or those that are moldy. Give the key limes a sniff – fresh ones should have a citrusy aroma.
Can I grow my own key lime tree?
Yes, you can grow your own key lime tree! Key lime trees are relatively low-maintenance and can thrive in containers or in the ground in USDA hardiness zones 10-12. Start with a grafted key lime tree from a nursery or online supplier, and plant it in well-draining soil with full sun to partial shade.
Water your key lime tree regularly, fertilizing it every few months with a citrus-specific fertilizer. Prune the tree regularly to maintain its shape and promote fruiting. Key lime trees can take 3-5 years to produce fruit, but with proper care, they can provide you with a bounty of fresh key limes for years to come.
How do I make key lime zest?
To make key lime zest, simply grate the outer, colorful layer of the key lime peel using a fine grater or microplane. Be careful not to grate too deeply, as the white pith underneath can be bitter. You can also use a zester or a vegetable peeler to remove the zest in strips, then chop it finely.
To dry key lime zest, spread it out on a baking sheet and place it in a low-temperature oven (150°F – 200°F) for 1-2 hours. Stir the zest halfway through to ensure even drying. Once dry, store the zest in an airtight container for up to 6 months. You can also freeze key lime zest for up to 1 year.
Are key limes and regular limes interchangeable in recipes?
While key limes and regular limes share some similarities, they are not entirely interchangeable in recipes. Key limes have a more intense, tart flavor and a stronger aroma than regular limes. Regular limes, on the other hand, have a more delicate flavor and a higher juice content.
In general, it’s best to use key limes in recipes that specifically call for them, such as key lime pie or key lime juice. If a recipe calls for regular lime juice, you can substitute it with key lime juice, but use less of it due to its stronger flavor. However, if you only have regular limes on hand, you can still use them in a pinch – just be aware that the flavor profile may be different.
