Curried herring spread (Karrysild)

Karrysild is a traditional spread originating from Denmark. This curried herring spread is usually made with a combination of marinated herrings, curry powder, mayonnaise, and crème fraîche or sour cream. The mayonnaise and crème fraîche are mixed together with curry powder, pickling liquid, salt, and pepper.

The herring is folded into the mixture, and it's then typically spread over sliced rye bread and topped with mustard. It's recommended to accompany the spread with boiled eggs and sliced onions on the side.
