Karintō (花林糖, karintō, (ateji)) is a traditional japanese snack food. sweet and deep-fried, it is made primarily of flour, yeast, and brown sugar. it has a deep brown and pitted appearance, and takes the form of a bite-sized pillow or short cylinder. although traditional karintō is coated with brown sugar, recently other variations appear in the market, such as white sugar, sesame seeds, miso, or peanuts.
