Tomato Sauce with Butter and Onions
Adapted from Marcela Hazanâ€™s Essentials of Italian Cooking
Another thing that blew my mind about this sauce: I, for one, am a grated parmesan junkie. I not only sprinkle it over my bowl of pasta, I like to have additional nearby, to apply a fresh coat to the layers of pasta that follow. So you can imagine my shock to find that I liked this dish even more without the parmesan. The flavor of the sauce is so delicate, fresh and sweet that it needed nothing at all.
Serves 4 as a main course; makes enough sauce to lightly coat most of a pound of spaghetti
28 ounces (800 grams) whole peeled tomatoes from a can (San Marzano, if you can find them)*
5 tablespoons (70 grams) unsalted butter
1 medium-sized yellow onion, peeled and halved
Salt to taste
Put the tomatoes, onion and butter in a heavy saucepan (it fit just right in a 3-quart) over medium heat. Bring the sauce to a simmer then lower the heat to keep the sauce at a slow, steady simmer for about 45 minutes, or until droplets of fat float free of the tomatoes. Stir occasionally, crushing the tomatoes against the side of the pot with a wooden spoon. Remove from heat, discard the onion, add salt to taste (you might find, as I did, that your tomatoes came salted and that you didnâ€™t need to add more) and keep warm while you prepare your pasta.
Serve with spaghetti, with or without grated parmesan cheese to pass.
* I liked this enough to make us more the next day, but I only had a can of tomato puree. It also worked well, despite having slightly less texture. You will need a little less simmering time as the tomatoes are already broken down.
