Finger Lime

Citrus caviar

Finger limes are the most distinctive citrus in the world. Cut one crosswise and squeeze gently — out come tiny round juice vesicles, perfectly separated, that look like translucent salmon roe. Each pearl pops in the mouth, releasing intensely tart citrus juice with a subtle floral note.

The technical term for these pearls is citrus caviar. The phenomenon results from the unusual structure of the fruit’s juice sacs — instead of fusing into segments like other citrus, they remain as individual units.

Aboriginal heritage

Finger limes are native to the rainforests of New South Wales and Queensland — Aboriginal peoples have eaten them for tens of thousands of years. Commercial cultivation began only in the 1990s as Australian growers recognized the fruit’s potential for export. They’re now grown in California, Florida, and elsewhere.

A fine-dining staple

Finger lime caviar appeared in high-end restaurants in the 2010s as a striking garnish:

• Oysters — pearls scattered on the half-shell.
• Scallops — bright counterpoint to the sweet flesh.
• Ceviche — the pearls hold their shape unlike free juice.
• Cocktails — gin & tonic with finger lime is a signature drink.

The pearls don’t dissolve in liquid the way regular juice does — they stay intact, popping when chewed. This makes them visually distinctive and texturally interesting in a way that no other citrus can match.

A premium price

Finger limes retail for $40–$80 per kilogram — among the most expensive citrus in the world. The cost reflects limited production and the labor-intensive harvest. The cost has driven exclusive use in fine dining and slowed mass-market adoption.
