What is "swedish meatball"?

Swedish meatballs are a traditional dish that is said to have been created by a Swedish-born chef in the late 1800s, or introduced to Sweden by King Charles XII. They are usually made with a combination of ground beef and pork, and topped with a creamy white sauce. The meatballs are extra tender and juicy due to the addition of ground pork, and have a springy yet delicate texture. The sauce is made from beef broth, cream, sour cream, and spices.
