Origin And History Of Finger Limes
From Australia To The Global Culinary Scene
Finger limes, also known as 'citrus caviar', are a unique fruit from Australia. They've been part of indigenous Australian diets for thousands of years but have only recently gained popularity worldwide. This exotic citrus is now loved by chefs and food enthusiasts for its versatility and distinctive taste. Finger limes are increasingly used by top chefs globally.
The Evolution Of Finger Lime Usage
Finger limes have deep roots in Aboriginal communities in Australia. For centuries, they were used as a food source and in cultural rituals and medicinal practices.
In recent decades, finger limes have moved from traditional uses to modern cuisine. Chefs are now incorporating them into haute cuisine, exploring the unique flavours they offer.
Today, you can find finger lime pearls in Michelin-starred restaurants, adding a unique burst of flavour to innovative recipes and contemporary dishes.
Understanding Finger Limes
A Botanical Overview
Finger limes, scientifically known as Citrus australasica, grow on small, shrubby trees that can be 2 to 7 metres tall. The leaves are small with notched tips. The fruit, which is 4 to 8 centimetres long, looks like a gherkin and comes in various colours, including pink and green.
Inside, the fruit has tiny, juice-filled pearls known as 'citrus caviar'. These pearls burst with flavour when eaten, making finger limes popular in cooking. This native Australian plant is not only interesting to look at but also has a unique taste.
Distinctive Flavours and Varieties
Finger limes are highly aromatic with a taste that chefs love. They have a flavour similar to classic lime but with herbaceous notes. There are many varieties, each with its own unique taste, from tart to slightly sweet, with hints of grapefruit or lemon.
Varieties have names like 'Pink Ice' and 'Blood Lime', which describe their different colours and flavours. The skin can be black-purple or pale green, and the pulp can be dark yellow-green or bright pink. Another variety, the 'Australian Desert Lime', is hardy and has a strong citrus flavour.
Finger limes come in various sizes, usually around 50mm x 25mm, and can be grafted or grown from cuttings. Each variety has its own unique characteristics.
