Written by on in Fruits

Finger lime is a small, elongated Australian native citrus whose pulp bursts into tiny, translucent, caviar-like vesicles with a tangy, slightly effervescent flavor. It is prized in haute cuisine as a natural garnish and textural element.

History & Origins

Finger lime was foraged and consumed by Indigenous Australians for thousands of years before European settlement. It was first formally described botanically in 1858 by Victorian government botanist Ferdinand von Mueller, and commercial cultivation only began in the 1990s as bushfood industry demand grew. Since the 2000s it has gained international recognition, marketed as 'citrus caviar,' and is now grown in California, Spain, and parts of Southeast Asia.
