Today’s cool tool is not actually a tool, but a food — more specifically, a fruit. It may, in fact, be my new favorite fruit! Introducing the SUMO CITRUS…

The Sumo Citrus is a Japanese hybrid of mandarin, Satsuma and navel oranges. With a distinctive top knot that is reminiscent of a sumo wrestler’s hairstyle (hence the name), it was developed over the span of 30 years and recently became one of the most prized citrus fruits in Japan and Korea, fetching up to $8 per fruit! Called the Dekopon in Japan and Hallabong in Korea, it is finally available in the U.S. thanks to a grower in California who uses the same exact standards of the original Japanese farmer.
