Crayfish has been eaten in Sweden since the middle ages and since the 1500s it has been mainly enjoyed by royalty at weddings and such. It wasn’t until the 1800s that crayfish were eaten as they are today – at crayfish parties where they are served whole, cold and cooked with dill. These crustaceans became a symbol for saying goodbye to summer and welcoming the fall. The term kräftskiva (crayfish party) and the festivities eventually became a national ritual in the early 1900s. They start in conjunction with the fishing season.
