In Sweden, meatballs are called kottbullar (which is now the first and only Swedish word I know), and they usually are made with ground beef or a mix of ground beef, pork and sometimes veal, and they are finished in a sauce of broth and cream.
While there are other Northern European meatball recipes that combine a gravy of sorts with meatballs, I think it's safe to say that most people (hand raised!) will associate these meatballs with Sweden (and Ikea) above all.
Kosher salt and ground black pepper
1 pound ground beef
