For a meat sauce or spaghetti and meat balls.....do you make a quick sauce or simmer for hours. Do you cook the meat balls in the sauce, or saute or oven roast first? I haven't mastered it yet, although I've tried at least once a week for many years. My sauce and meatballs do not taste like the best I've had in Italian restaurants. "Gravy" and meatball help please?
