Inlagd sill or pickled herring is a Swedish fish dish that has long been served in Sweden at Midsummer, Christmas, and Easter celebrations. The dish consists of cleaned, skinned, and salted herring that is soaked in a marinade of vinegar, sugar, chopped onions and carrots, allspice, bay leaves, pepper, and crushed peppercorns.

Before serving, the fish is cut into thick slices and it is traditionally garnished with minced red onion and sprigs of fresh dill. As always, Swedish snaps (shots of strong alcoholic beverages) are more than welcome to accompany this dish.
