Everyone likes spaghetti But everyone makes their sauce a little differently. I want to know what you put in yours, and more specifically what you don't. Classic American spaghetti sauce usually includes: ground beef, onion, garlic, green bell pepper, diced tomatoes, tomato sauce, tomato paste, oregano, basil, salt & black pepper. Classic Itallian spaghetti bolognese is pretty different because it's primarily a meat sauce and not tomato based. Different ingredients it usually includes are: Olive oil, bacon, minced beef, carrots, celery, rosemary, thyme, milk and red wine. The spaghetti sauce I make (and am making right now) is a mix between the two styles, different ingredients I use are mushrooms, spinach and cinnamon. What do you guys use?
