This yellow-and-white spin is named for the aromatic citrus fruit whose acidic rind and juice are often used in Japanese cuisine! It is tart and fragrant, closely resembling a grapefruit's flavor, with overtones of mandarin orange, and is an integral ingredient in ponzu sauce, which is often served alongside sushi and tempura dishes...Yuzu even smells sooooooo yummy that it is used both in perfumes and Japanese ritual baths during Toji (the winter solstice)!
