Finger lime varieties. Finger limes are a micro-citrus originally discovered growing wild in Australia. The interior pulp can best be described as citrus pearls, or citrus caviar.

The flavor is similar to that of a lemon-lime-grapefruit combo, the juice bursts from the citrus pearls when bitten into.
