"Maustekala" is a Finnish marinated delicacy made from small Skippers (Sprattus sprattus). Also you can use Baltic herring (Clupea harengus membras). Here in Spain I have used Sardelles (Engraulis encrasicolus) also called Anchovy and making them from fresh and small fish fillets to avoid Anisakis.
When you have available small Baltic Skippers, you only wash them and dry.
