Sumo Citrus is a type of citrus fruit (sometimes called Sumo Mandarins or Sumo Oranges) that looks like a smaller version of the -slightly- larger navel orange. In fact, they are a mostly-seedless cross between Satsuma Mandarins and navel oranges, which you might think of as the classic oranges you ate cut into wedges as a kid or buy in bulk to make fresh orange juice on Sunday mornings. The great thing about Sumo Citrus is its unique sweetness — it’s much, much sweeter than oranges and clementines.
Navel oranges are large and exceptionally juicy, but they have a tight peel that can be hard to get off. The Sumo Citrus has that same succulent, juicy quality, but with the looser, easy-to-peel skin of a mandarin.
In Japan, where the fruit is known as Dekopons, these large and juicy citrus fruits are beloved enough that people exchange them as gifts, much as one might send a relative a box of ripe navel oranges after a trip to Florida.
These days, Sumo Citrus is easy to find in local supermarkets. It’s definitely a little more expensive than other citrus, but totally worth it.
When you do find Sumo Citrus in stores, don’t put it through the juicer. Instead, take advantage of its easy peel nature and bring it with you to work or school.
