This is a delicious meatball recipe with a dill and sour cream sauce. The recipe is similar to a Swedish meatballs recipe, although the seasoning is a little different.
Combine bread crumbs and milk and set aside. Melt 4 tablespoons butter in a small skillet.
Add onion and sauté until golden brown. In a mixing bowl combine ground chuck, egg yolks and cooked onion. Squeeze any excess milk from bread crumbs and add crumbs to meat. Add all of the seasonings. Mix thoroughly with your hands.
Shape mixture into small even balls. Press a tiny lump of firm butter into the center of each ball. Roll balls in dry bread crumbs. Pat well in hands so the crumbs will stick. Chill for 30 minutes so that crumbs will stick to the meatballs a little better.
Melt 4 tablespoons of butter in a large skillet. Add meat balls and cook until golden brown on all sides and cooked through. Remove meatballs to a hot serving dish and keep warm.
Pour off almost all the fat from the skillet. Stir in the sour cream, lemon juice and chopped dill. Heat, scraping bits from bottom of skillet, but do not boil. Taste for seasoning. Pour the sauce over the meatballs.
