Haring, or Dutch herring, is a popular seafood delicacy in Amsterdam. It is a raw fish dish made from young herring that has been lightly salted and cured. The herring is typically served whole, with the head and tail intact, and eaten by holding it by the tail and taking small bites. It is often enjoyed with chopped onions and pickles. Haring is a must-try for seafood lovers visiting Amsterdam, and it is commonly found at fish stands and street food vendors throughout the city.
