Swedish meatballs in cream sauce (köttbullar med gräddsås)

“There’s no more identifiably Swedish dish than good old Swedish meatballs. There are a few keys to a good meatball – steam the meatballs so they are tender, fry them in brown butter, then combine them with the sauce just at the last minute. They are perfect with pickled cucumber and lingonberry jam.” Adam Liaw, Destination Flavour Scandinavia
