Daidai

Daidai is a type of bitter orange (Citrus aurantium) originating from Southeast Asia. It is widely cultivated in Japan and other East Asian countries. The fruit is characterized by its bright orange rind and a distinctly bitter flavor, making it less commonly consumed fresh compared to sweet oranges. Historically, daidai has been used in various culinary and traditional applications.

In Japanese cuisine, daidai is a key ingredient in ponzu sauce, a popular condiment that provides a citrusy and tangy flavor to dishes. The juice and zest are often incorporated into marinades, dressings, and savory sauces. Beyond its culinary uses, daidai is also valued for its aromatic properties and has been used in traditional medicine. The rind can be dried and used as a fragrance or in potpourri. In some cultural practices, daidai is associated with New Year celebrations in Japan, symbolizing good fortune and prosperity. The tree itself is ornamental and produces abundant fruit.
