Korokke is a variety of Japanese deep-fried dishes that are a version of the French dish called croquette. It consists of a combination of mashed potatoes and chopped meat, seafood, or vegetables. The combination of those ingredients is shaped in a patty and rolled in flour, eggs, and breadcrumbs, then deep-fried.
It is said that the French croquette was introduced to Japan in 1887, but today it can be found in almost every supermarket and store in Japan, since it is inexpensive, yet very tasty and flavorful. With its huge popularity, there is also a number of korokke varieties including potato, meat, tuna, curry, cream, and okara korokke.
