Amanatsu oranges are medium to large, similar in size to a navel orange or grapefruit, and are globular to oblate in shape. The orange-yellow rind is smooth, leathery, fragrant, and covered in prominent oil glands giving the surface a pebbly appearance. Underneath the rind, there is a semi-thick white pith that is spongy and easily peeled. The flesh is soft, orange, divided into 10-12 segments, and contains many cream-colored seeds. Amanatsu oranges are aromatic and have a sweet and sour flavor.
Seasons/Availability
Amanatsu oranges are available in Japan in the late spring through summer.
Current Facts
Amanatsu oranges, botanically classified as Citrus natsudaidai, are a sour hybrid variety that belongs to the Rutaceae or citrus family. Also known as the Japanese Summer orange, Natsudaidai, and Natsumikan, Amanatsu oranges are believed to be a hybrid of a pomelo and sour orange and are native to Japan. Amanatsu oranges can be extremely sour and are typically harvested and stored for a short period before they are consumed. This storage period reduces the acid within the flesh creating a sweet-tart flavor. Favored for their bright flavor and fragrant zest, Amanatsu oranges are often used fresh and are a staple ingredient in Japanese cooking.
Nutritional Value
Amanatsu oranges are an excellent source of vitamin C and potassium and are a good source of folate, niacin, magnesium, and vitamin B1.
Applications
Amanatsu oranges are best suited for fresh eating, and the juice and zest are also used to flavor cooked applications. The rind is easily peeled, and the flesh can be divided into segments as a stand-alone snack. The fruit can be juiced and makes a refreshing beverage that can be used for cocktails, wine, or blended with other citrus juices. Amanatsu oranges are also used for making marmalade, ice cream, sherbets, and the rind is often candied. In Japan, individual segments are removed from their pith and served in a clear jelly. Amanatsu oranges pair well with poultry, fish, sashimi, asparagus, green beans, dark leafy greens, mushrooms, rice, noodles, almonds, peanuts, and walnuts. The fruits will keep 2-4 weeks when stored in the refrigerator.
