Marcella Hazan's Tomato Sauce with Onion and Butter

Note to self- take photos before you put food on the table. So this was so good it was gone before I could snap a photo. A few weeks ago, my sister appeared at my door with a few tomatoes. They were perfectly ripe. I made Marcella Hazan's Tomato Sauce with Onion and Butter. I blended the onion into the sauce with an immersion blender. The sauce went into the freezer until tonight. Oh My God. It could have been that we have not had home made sauce with spaghetti for quite some time but there were no leftovers. That bit of sauce in the pan disappeared with the last of the Italian bread.
