1. What Are Japanese Citrus Fruits?
Kabosu, yuzu, and sudachi are part of a family of aromatic, sour citrus fruits known as kōsan kankitsu (香酸柑橘) in Japan. Rich in limonene (for aroma) and citric acid (for sourness), they’re not meant to be eaten like oranges but are used to enhance dishes with their refreshing scent and tang.
