Introduction – Meet the Finger Lime
If fruits could be called gemstones, the finger lime (Citrus australasica) would be the sparkling emerald of the citrus world. This small, elongated fruit is native to the rainforests of Queensland and New South Wales, Australia, and has been a cherished food of Indigenous Australians for thousands of years.
Today, it’s loved by chefs, foodies, and health enthusiasts for its citrus caviar-like pearls that burst with tangy, refreshing flavor.
In this guide, we’ll explore everything about finger limes — from their history and nutritional benefits to their culinary uses, growing tips, and a bonus recipe that will make you fall in love with this exotic fruit.
1. What is a Finger Lime?
Finger lime is a subtropical citrus fruit shaped like a small finger (hence the name), usually 4–8 cm in length. Its outer skin can be green, brown, red, or even purple, depending on the variety. Inside, instead of the usual citrus segments, you’ll find tiny juice vesicles — often called citrus pearls — that look like caviar.
These pearls range in color from pale green to pink, red, or even champagne, and their texture and flavor make them a gourmet delicacy.
Fun Fact: Some chefs call finger lime “lime caviar” because the vesicles pop in your mouth like luxury seafood caviar — but they’re vegan and plant-based.
2. Origin and History
Finger lime is indigenous to Australia, where it grows in the coastal rainforests and lowland subtropical forests.
For thousands of years, Indigenous Australians gathered finger limes as a seasonal food, eating them fresh or as a tangy addition to seafood and game meats.
In recent decades, finger limes have transitioned from wild bushfood to a commercial crop, thanks to gourmet chefs and export demand. Today, they are farmed in Australia and exported to Europe, Asia, and North America.
