The Yuzu is a citrus fruit originating in East Asia. It can typically grow from 10-20 ft. high with foliage similar to other citrus trees. It is believed to be a hybrid of a sour mandarin and Ichang papeda. The fruit looks a bit like a very small grapefruit with an uneven skin, and can be either yellow or green depending on the degree of ripeness. It is unusual among citrus fruits in being relatively frost-hardy where more sensitive citrus would not thrive.

The yuzu's aromatic zest and juice has a unique tart citrus flavor and is a popular ingredient in Japanese cooking. An integral ingredient in Ponzu sauce.
