Finger Limes 101 – How To Use, Buy, Store In Easy Way

What are Finger Limes

Finger limes, also known as “citrus caviar” or “caviar limes,” are a unique type of citrus fruit native to Australia. Scientifically known as Citrus australasica, finger limes are small elongated fruits that range in size from about 2 to 4 inches (5 to 10 centimeters) in length. They get their name from their appearance, resembling small, slender fingers.

What sets finger limes apart is their distinctive texture and flavor. When the fruit is cut open, it reveals tiny juice-filled vesicles that look similar to caviar, which is why they’re sometimes called “citrus caviar.” These juice-filled pearls are often used as a flavorful and visually appealing garnish in culinary dishes.

Finger limes come in various colors, including green, yellow, pink, and red, and their flavor profile can range from tangy and tart to mildly sweet, depending on the variety. The pearls burst in the mouth, releasing a burst of tangy citrus flavor.

Due to their unique texture and flavor, finger limes have gained popularity among chefs and culinary enthusiasts for their use in dishes, desserts, and even as a topping for seafood. They add an extra layer of flavor and texture to a variety of foods and drinks.

Finger lime trees are grown in several countries, primarily in Australia, but they are becoming more widely cultivated in other regions as well. They thrive in subtropical and tropical climates and require well-draining soil and plenty of sunlight.

Why Is It Called Finger Lime

Finger limes are called so because of their appearance. The fruit is elongated and slender, resembling small fingers or elongated capsules. When the fruit is cut open, it reveals the unique structure of the vesicles, which are filled with juice.

These vesicles look like small pearls or beads, similar to caviar. The combination of the elongated shape and the caviar-like texture of the vesicles led to the name “finger lime.” The name is a descriptive term that captures both the shape of the fruit and its distinctive internal structure.

Do Finger Limes Taste Like Limes

Yes, finger limes do have a citrus flavor similar to regular limes, but their taste can also have some variations depending on the specific variety and ripeness. The overall taste profile of finger limes is tangy and citrusy, much like traditional limes, but there might be differences in sweetness, tartness, and other subtle flavor notes.

What sets finger limes apart from regular limes is their unique texture. When you cut open a finger lime, you’ll find small juice-filled vesicles that resemble caviar or pearls. These vesicles burst in your mouth, providing a burst of tangy and refreshing citrus flavor. This texture experience, along with the citrusy taste, makes finger limes a distinct and sought-after ingredient in culinary creations.

So, while finger limes share some flavor characteristics with regular limes, it’s their texture and the way they release their juice that truly make them stand out.

Why Are Finger Limes Expensive?

Finger limes are often considered a specialty or niche fruit, and there are several reasons why they can be expensive:

1. Limited Availability: Finger limes are native to Australia and have historically been found in specific regions. Their cultivation and availability have expanded to other parts of the world, but they are still relatively rare compared to more common citrus fruits. Limited production can contribute to higher prices.
2. Challenging Cultivation: Finger lime trees have specific requirements for growth, including subtropical to tropical climates with well-draining soil and adequate sunlight. Cultivating and maintaining these trees can be more challenging than other citrus varieties, which can impact their supply and pricing.
3. Labor-Intensive Harvesting: Harvesting finger limes is a delicate process due to their small size and the need to preserve the integrity of the individual vesicles. Each tiny “lime caviar” needs to be carefully harvested by hand, which can be time-consuming and labor-intensive.
4. Perceived Value: Finger limes are often considered a gourmet ingredient due to their unique texture and appearance. This perception of exclusivity and the distinctive culinary experience they offer can contribute to their higher price point.
5. Transportation and Shelf Life: Finger limes have a relatively short shelf life compared to some other citrus fruits. They can be delicate and susceptible to damage during transport. Ensuring that they arrive at their destination in good condition can involve careful handling and specialized packaging, which can add to the cost.
6. Growing Conditions and Yield: The yield of finger lime trees can vary based on factors like climate, soil quality, and care. If conditions aren’t optimal, the yield may be lower, which can impact the overall supply and pricing.

All these factors—limited availability, cultivation challenges, labor-intensive harvesting, perceived value, transportation considerations, and variable yields—can contribute to the higher cost of finger limes compared to more common citrus fruits. As demand for unique and gourmet ingredients grows, finger limes continue to be prized by chefs, food enthusiasts, and those looking for a distinctive culinary experience.

How to Store Finger Limes

Finger limes are delicate and have a relatively short shelf life compared to some other citrus fruits. Proper storage is important to keep them fresh and maintain their flavor and texture. Here’s how to store finger limes:

1. At Room Temperature: Finger limes are best stored at cool room temperature, around 50-68°F (10-20°C), if you plan to use them within a day or two. Avoid direct sunlight and heat sources.
2. Refrigeration: If you don’t plan to use the finger limes immediately, it’s recommended to store them in the refrigerator. Place them in the vegetable crisper drawer, where the temperature is slightly cooler and humidity is higher.
3. Proper Packaging: To prevent moisture loss and maintain freshness, place the finger limes in a perforated plastic bag or a container with a lid. You can also wrap them in a slightly damp paper towel and then place them in a plastic bag.
4. Avoid Humidity: While some humidity is beneficial, excessive moisture can lead to mold growth. Make sure the storage container allows for some air circulation to prevent moisture buildup.
5. Separation: Keep the finger limes separate from other fruits and vegetables to prevent any unwanted flavors or aromas from being absorbed.
6. Use Quickly: Finger limes are best used within a week of purchase or harvest for optimal flavor and texture. The longer they are stored, the more their quality may deteriorate.
7. Freezing: If you have an abundance of finger limes, you can freeze the juice-filled pearls for later use. Gently squeeze out the pearls from the fruit and place them in an airtight container or freeze them on a tray and then transfer to a freezer bag. Frozen finger lime pearls can be used in drinks and dishes directly from the freezer.

Remember that the delicate nature of finger limes means they may start to lose their texture and flavor over time, so it’s best to enjoy them as fresh as possible. Always inspect them before use to ensure they haven’t started to deteriorate.
