Ask a Dago abouto marinara sauce and I will tell ya....
1/2 cup extra-virgin olive oil
2 small onions, finely chopped
2 garlic cloves, finely chopped
2 stalks celery, finely chopped
1/2 teaspoon sea salt
1/2 teaspoon freshly ground black pepper
2 (32-ounce) cans crushed tomatoes or 10 romano tomato or 4-6 beef steak tomatos for good measure throw a handful of cherry tomatos for flavor. Just chop up the tomatos and squish them with your hands or put them in a zip lock bag and beat the crap out of the tomatos with a hammer, malt, bottom of a wine bottle or anything with a blunt surface.
2 dried bay leaves
In a large sauce pan, heat the oil over a medium-high flame. Add the onions and garlic and saute until the onions are translucent, about 10 minutes. Add the celery and 1/2 teaspoon of each salt and pepper. Saute until all the vegetables are soft, about 10 minutes. Add the tomatoes and bay leaves, and simmer uncovered over low heat until the sauce thickens, about 1 hour. Remove and discard the bay leaf. Season the sauce with more salt and pepper, to taste. (The sauce can be made 1 day ahead. Cool, then cover and refrigerate. Rewarm over medium heat before using.)
