Which cuisine does the dish "vorschmack" belong to?

THIS DISH IS GREAT! I GREW UP ON IT. WE ARE JEWS OF THE UKRANIAN RUSSIAN AREA SO ITS ACOMMON APPETIZER.

K O T K, read the description.

My Uncle Mike would always bring a gallon jar of pickled herring to EVERY family get together! Took a little getting used to…but now as an adult I truly appreciate this healthy appetizer!
