An Australian bushfood turned fine-dining star — its juice comes as tiny bursting pearls, "citrus caviar".
How to select & store
Picking a ripe one
Choose firm, unblemished fruit in shades of green, red, pink, or black by cultivar. A slight give means ripe. It bruises easily, so handle the small finger-shaped fruit gently.
Storing it
Refrigerate whole for up to two weeks. Once cut, the pearls dry out, so slice and squeeze them out just before serving. The pearls also freeze reasonably well for later garnish.

- Its caviar-like pearls made it a symbol of the modern native-food movement
The finger lime is citrus reinvented as caviar. Native to the rainforests of eastern Australia and shaped like a short, knobbly finger, it splits open to release not juice but hundreds of tiny, firm, translucent pearls — each a self-contained bead of sharp lime-and-grapefruit tang that pops between the teeth. The texture is the point, and no other citrus offers it.
Bushfood to fine dining
Aboriginal Australians ate finger limes as bush tucker for millennia, valuing them for food and vitamin C. In recent decades chefs rediscovered them, and the “citrus caviar” — scattered over oysters, sashimi, cocktails, and desserts — became a symbol of the modern native-food movement and a prized garnish on fine-dining plates worldwide.
Handle the pearls with care
Cultivars range from green to red, pink, and near-black flesh, each with slightly different notes. The one rule: keep the fruit whole until service, then slice and squeeze the pearls out at the last moment, since exposed beads dry quickly. Alongside yuzu and calamansi, the finger lime rounds out the world’s roster of specialty citrus prized as much for character as for juice.
