Brilliant bare-ass-simple tomato sauce recipe we've started using recently:1 28 oz. can San Marzano tomatoes1 medium onion5 Tbsp. butterPour tomatoes in medium sauce pan. Add butter. Peel onion and cut in half along the hemisphere. Deposit halves in sauce. Simmer for 45 mins or until the onion gets mushy and fat is visible as small droplets throughout the sauce. As you check on it, you can smoosh the tomatoes against the side of the pot, but they'll mostly melt on their own. Remove onion and add salt, pepper, and possibly sugar to taste. Serve over pasta.
Just so Loundry doesn't accidentally try this recipe, credit needs to go to Marcella Hazan on this one. And I agree that it is wonderful - way more than the sum of its parts.
