What is yuzu?

Yuzu (柚子 in Japanese) is a citrus fruit that has been grown in Japan since ancient times. "Yellow yuzu" are harvested when the fruit is ripe and yellow in color, whereas "green yuzu" are harvested before ripening. Yellow yuzu are generally in season around November. Thinly scrape or grate off only the yellow part of the peel and add it to dishes such as clear soups and chawanmushi (savory egg custards) as a flavoring, or add soy sauce to the squeezed juice to make ponzu sauce. Yuzu can even be added to dressings and also be enjoyed as marmalade, candied fruit, fruit wine, liqueur, and desserts such as sorbet and jelly.

Nutrition facts

Yuzu is rich in vitamin C. Yuzu peel in particular contains more vitamin C than that of lemons, and its strong antioxidant properties help improve immunity and support healthy skin. This citrus also contains a lot of citric acid, which helps with recovery from fatigue and to promote energy metabolism. The peel and rind are rich in dietary fiber and pectin, which help regulate the intestinal environment.
The white pith of yuzu is rich in hesperidin, which contributes to maintaining healthy blood vessels. In addition, the aromatic component, limonene, has a relaxing effect, improves blood circulation, and helps increase appetite.
To effectively consume yuzu nutrients, ideally use raw with the peel on. The peel, which contains a lot of vitamin C and limonene, can be finely chopped and used in dressings and salads to preserve its aroma and nutrients.

Storage to prevent food loss

Wrap yuzu in kitchen paper and place in a plastic bag to store in the refrigerator for up to 10 days. Feel free to also cut the fruit in half, cover in plastic wrap, and store in the freezer for up to one month.
