Known as the caviar of citrus, the finger lime is an Australian fruit that’s gaining popularity in the United States. The inside of the fruit contains round vesicles of juice that pop on the tongue, and pikawicca describes the flavor as a tart combination of lime and lemon. “These little things are really fun and tasty,” says pikawicca. “So far we’ve had them on tuna sashimi and dancing around a flute of champagne; tonight it’s in a caviar/champagne sauce over scallops.”

It’s possible to order the fruit online, but as celeriac reports, finger limes are now available at Formaggio Kitchen in Cambridge. The current price at Formaggio Kitchen is $75 per pound, but since the fruits are very small (each weighs in at less than an ounce), buying a few won’t break the bank.
