Sudachi is a small, aromatic citrus fruit originating from Japan. It's about the size of a golf ball and has a tart and refreshing flavor with notes of lime and lemon. Sudachi is used in various Japanese dishes and is famous for its unique flavor and versatility in cooking. What is Sudachi? Sudachi (pronounced "soo-dah-chee") is a small Japanese citrus fruit. It belongs to the same family as yuzu and kabosu, and is a popular ingredient in Japanese cuisine. Sudachi is about the size of a ping-pong ball and has green-yellowish skin that is thin and bumpy. The fruit's flesh is also green and divided into several segments. The juice of sudachi is tart and acidic, with a bright, citrusy flavor similar to a combination of lime and lemon. In Japanese cuisine, sudachi is often used as a garnish or seasoning and is commonly paired with seafood, ramen soups, soba and udon noodles, alcoholic beverages, and salad dressings. Sudachi is typically harvested in the late summer and early fall, and is primarily grown in the Tokushima and Kochi prefectures in Japan. In recent years, it has also been cultivated in other parts of the world, including the United States and South America. The History of Sudachi The Sudachi citrus was originally grown in Tokushima Prefecture on Japan's Shikoku Island. Even now, 98% of the citrus sold in Japanese markets is produced in Tokushima. Rumor has it was accidentally discovered when two citrus fruits, Yuzu and another unknown citrus (possibly Tachibana or Koji), mixed and created a new type of citrus. Sudachi was initially rare and only available to wealthy people and high-end restaurants in Tokushima. Over time, it became more widely available throughout Japan and is now a popular flavoring ingredient for chefs worldwide. Sudachi is considered a luxury fruit outside of Tokushima and is often sold at high prices in Japan. It was introduced to American growers in 1963 by a botanist from California who visited Japan to learn about Japanese citrus varieties. More recently, a unique variety of sudachi has become more widely grown in California, and it can be found through select specialty growers and distributors. Sudachi's are prized in Japanese cuisine for their juice which pairs perfectly with seafood. What Does a Sudachi Taste Like?
