Finger Lime
Citrus australasica
Cut one open and it doesn't behave like a lime. Instead of segments there are hundreds of tiny juice beads that spill out whole and hold their shape until you bite them. They pop. That's why chefs call it citrus caviar, and why it reached tasting menus before most Australians had ever tried one.
The flavour is lime and grapefruit at once, sharper than either, with a faint bitterness at the edge like grapefruit pith. Because the beads stay intact, it seasons food without wetting it — which is the whole trick. A spoonful over oysters, sashimi or a scallop does what a wedge of lime does, but dry, and in bursts.
Best raw: over seafood, stirred through butter, in cured fish, in a dressing, in a gin and tonic. Don't cook it. Heat collapses the beads and you lose the point of it.
Finger limes come from the rainforest margins of southern Queensland and northern New South Wales. Ours grow a long way from there, in central Victoria, where frost is normal in winter and forty degrees is not unusual in summer. They are young and frost-tender for the first few years, and they are the best-performing planting on the farm.
First real crop: two to three years away.
