Finger limes, also known as “citrus caviar,” are a type of citrus fruit that grows on the finger lime tree (Microcitrus australasica). The fruit is characterized by its elongated, finger-like shape, typically ranging from 3 to 12 centimeters in length. The skin of the finger lime is thin and fragile, enclosing a pulp filled with tiny, juice-filled vesicles that resemble caviar. These vesicles, also known as “pearls,” are the edible part of the fruit and are highly prized for their burst of citrus flavor.
Nutritional Value of Finger Limes
Finger limes are a nutrient-rich food, providing a range of essential vitamins, minerals, and antioxidants. They are an excellent source of vitamin C, with a single serving providing up to 40% of the recommended daily intake. Finger limes are also rich in potassium, folate, and fiber, making them a great addition to a healthy diet. The antioxidant properties of finger limes have been shown to have potential health benefits, including reducing inflammation and improving cardiovascular health.
Culinary Uses of Finger Limes
The unique flavor and texture of finger limes make them a versatile ingredient in a variety of culinary applications. They can be used as a garnish, adding a burst of citrus flavor to dishes such as seafood, salads, and cocktails.

Cut the finger lime in half lengthwise, taking care not to squeeze the fruit and release the pearls.
Gently scoop out the pearls using a spoon or your fingers, being careful not to damage the delicate vesicles.

Use the pearls immediately, or store them in an airtight container in the refrigerator for up to 24 hours.
Potential Health Risks Associated with Finger Limes
While finger limes are generally considered safe to eat, there are some potential health risks associated with their consumption. The most significant risk is the potential for allergic reactions, as some people may be allergic to the proteins found in citrus fruits. Additionally, the high acidity of finger limes can cause digestive issues in some individuals, such as heartburn or stomach upset. To minimize the risk of adverse reactions, it is recommended to start with small amounts and monitor your body’s response.

What are finger limes and where do they come from?
Finger limes are a type of citrus fruit that is native to Australia, particularly in the subtropical and tropical regions of the eastern coast. They are also known as “citrus caviar” due to their unique appearance, with small, round vesicles that resemble caviar. Finger limes are a popular ingredient in modern Australian cuisine, and their unique flavor and texture have gained popularity worldwide. They are often used as a garnish or added to dishes for their burst of citrus flavor.
The finger lime tree is an evergreen shrub or small tree that grows up to 10 meters tall, with dark green, glossy leaves and small, white flowers. The fruit is typically harvested between May and October, and it is usually picked when it is still green, as it will continue to ripen after being picked. Finger limes are a versatile ingredient and can be used in a variety of dishes, from savory to sweet. They are a great addition to many recipes, and their unique flavor and texture make them a valuable ingredient for chefs and home cooks alike.
How do I choose the best finger limes for cooking?
When choosing finger limes, there are a few things to consider to ensure you get the best ones for cooking. First, look for limes that are firm and heavy for their size, as this indicates they are full of juice and will have the best flavor. The skin should be a deep green color and free of blemishes or soft spots. It’s also a good idea to give the lime a gentle squeeze to check for freshness – a fresh finger lime will be slightly yielding to pressure but still firm.
In terms of size, finger limes can vary from about 3 to 10 centimeters in length, and the size will not necessarily affect the flavor or quality. However, larger limes may have a more intense flavor and be easier to squeeze for their vesicles. It’s also worth noting that finger limes can be stored in the refrigerator for up to two weeks, so even if you can’t find them fresh, you may be able to find them in specialty stores or online. When storing finger limes, keep them away from direct sunlight and heat sources, and make sure they are not touching each other to prevent moisture from accumulating and causing spoilage.
What is the best way to extract the vesicles from finger limes?
The best way to extract the vesicles from finger limes is to cut the lime in half lengthwise and then squeeze the vesicles out using a gentle pressing motion. This can be done using your fingers or a spoon, and it’s a good idea to do this over a bowl or other container to catch the vesicles as they are released. Another way to extract the vesicles is to use a citrus squeezer or a juicer, but be careful not to apply too much pressure, as this can cause the vesicles to burst and lose their unique texture.
It’s also possible to extract the vesicles from finger limes by freezing them first and then squeezing them while they are still frozen. This will help to loosen the vesicles from the membrane and make them easier to remove. Once the vesicles are extracted, they can be used immediately or stored in an airtight container in the refrigerator for up to a week. It’s a good idea to rinse the vesicles with cold water before using them to remove any bitterness or excess juice. Finger lime vesicles can be used in a variety of dishes, from seafood to desserts, and their unique flavor and texture make them a valuable ingredient for chefs and home cooks alike.
Can I grow my own finger lime tree at home?
Yes, it is possible to grow your own finger lime tree at home, provided you have the right climate and conditions. Finger lime trees prefer well-drained soil and full sun to partial shade, and they thrive in warm, subtropical, and tropical regions. They can be grown in containers or in the ground, and they require regular watering and fertilization to promote healthy growth. It’s a good idea to choose a dwarf or compact variety of finger lime tree if you plan to grow it in a container, as these will be more compact and easier to manage.
To care for your finger lime tree, make sure to water it regularly, but avoid overwatering, which can cause the roots to rot. Fertilize the tree regularly with a citrus-specific fertilizer, and prune it annually to promote healthy growth and fruit production. Finger lime trees can be susceptible to pests and diseases, such as aphids, mealybugs, and root rot, so keep an eye out for these and take action if necessary. With proper care and conditions, a finger lime tree can produce fruit within 2-5 years, and it will continue to produce fruit for many years with proper care and maintenance. Growing your own finger lime tree can be a rewarding experience, and it will give you a steady supply of fresh finger limes to use in your cooking.
