Töölauke
Töölauke is a traditional Finnish dish consisting of thinly sliced, cured or dried fish, typically perch or roach, often served with a simple sauce or accompaniments. The preparation methods can vary regionally, but a common approach involves salting and drying the fish for preservation and to achieve a firm texture. The fish is then often lightly fried or simply served as is.
Historically, Töölauke was a practical way to preserve fish, a readily available resource in Finland, for consumption
