If using fresh herring, make sure it is cleaned and gutted. If using pickled herring, simply rinse under cold water to remove excess brine.
Place the herring on a cutting board. Using a sharp knife, cut the fish into bite-sized pieces, or you can serve it whole if preferred.
Lightly season the herring pieces with coarse sea salt and freshly ground black pepper.
Arrange the herring on a plate.
Sprinkle finely chopped onion over the top. Add chopped pickle or parsley if desired.
Herring is traditionally served with rye bread or raw onions.
For an authentic Dutch experience, you can also serve herring with a side of small pickles and fresh dill.
Enjoy your meal!
