Marcella Hazan and an amazing cook and foodie passed it on to me.
This would be great to use in a pasta dish - like lasagna - or just in spaghetti, like we did. I also added ground beef and grated parmesan to our spaghetti but it would have been delicious on it's own.
1 28-ounce can crushed tomatoes
1 onion, peeled and cut in half
5 tbsp. butter
Combine all ingredients and simmer gently for 45 minutes. Discard onion and season with salt and pepper to taste.
