While at a local grocery store this week, I asked if they had any blood oranges in stock, since this is prime time for their appearance at the market. The perplexed produce clerk pointed to a pyramid of orange fruit and suggested I look in the nearby bin. Unfortunately, I didn’t see any of the orange-skinned, ruby-fleshed citrus fruits, but I did discover a wide selection of knobby-skinned oranges labeled “Sumo Citrus.”
The hybrid known as Sumo Citrus was originally cultivated in Japan in the 1970s by a single grower who developed the fruit’s distinctive qualities. By 1998, it was imported by growers in California's San Joaquin Valley, and by 2010, the varietal was in commercial production in the United States. In 2022, the company enjoyed its best year, delivering the largest volume of these special fruits to markets across the country, and interest has continued to expand.
Farmers that produce these fruits describe the labor-intensive steps for growing the juicy gems. The citrus are allowed to ripen on the trees, which are hand-pruned. At harvest time, they’re hand-picked into small totes instead of large bins. They’re floated along the collection and inspection lines to prevent bruising while they’re sorted by size. Finally, they’re hand-packed into crates for shipment.
The fruit was originally nicknamed the “dekopon,” a reference to the distinctive topknot on the stem end of the fruit, which you can see in the photo. While some citrus are perfectly round, Sumo Citrus are slightly elongated with a wide, round bump. Unlike navel oranges or tangerines, the skin of the Sumo Citrus is noticeably bumpy, which is one of its signature features.
Sumo Citrus are also seedless, reliably sweet, easy to peel, and a delicious ingredient in any recipe calling for an orange or its juices. The smaller specimens in the photo came in a net bag that labeled them mandarins, while the larger one in the middle was in a bin with nothing more than a sign stating “Sumo Citrus.” They are actually a hybrid of navel oranges, pomelos and mandarins.
Beyond orange juice, and its lovely cocktail companion, champagne, poured into a flute for a mimosa, where else will you find oranges as ingredients in recipes? One of the most familiar is in a sweet application, such as pound cake, cranberry cupcakes, or chiffon-style cake brightened with both zest and juice from your favorite orange variety. Another is in creamy carrot soup, where the zest and juice are added as a final stir into the creamy mix.
One of the most familiar places to find spicy and slightly sweet orange flavors is in the Chinese-restaurant favorite known as orange chicken. I’ve included a recipe adapted from Modern Honey, which separates the frying step from the addition of the orange-forward sauce. This is delicious over Basmati or jasmine rice, garnished with orange zest. No matter your preference for orange varieties, be sure to give the Sumo Citrus a chance – not the prettiest fruit in the bin, but definitely delicious.

Orange Chicken*
4 boneless, skinless chicken breasts
1/3 C cornstarch
1/3 C flour

3 eggs, beaten
Oil for frying

1/3 C sugar
2 T rice wine vinegar

Trim chicken breasts and cut into bite-sized pieces; set aside. Combine flour and cornstarch in a shallow dish; add a generous pinch of salt and stir. Place beaten eggs in shallow bowl. Dip chicken pieces in egg mixture and then coat with flour mixture; set on a piece of waxed paper. Heat 2-3 inches of oil in a heavy-bottomed pot over medium-high. When temperature reaches 350 F, add several pieces of chicken. Cook for 2 to 3 minutes, turning often, until golden brown. Place chicken on a paper-towel-lined plate to drain. In a medium pot, combine orange juice, sugar, vinegar, soy sauce, ginger, garlic and pepper. Cook over medium heat for 3 minutes. In a small bowl, whisk cornstarch with water to form a paste. Stir into orange mixture and continue to cook for 5 minutes, until sauce begins to thicken. Remove from heat and add orange zest. Toss chicken with orange sauce and serve over rice.
