A brief tirade from someone quite invested in this recipe:do not muck about with this the first time. The second time, throw in some garlic, a bit of oregano, whatever you want. I certainly did. Be aware, however, that you will always return to this starting point. And no matter what you do to it, it will never taste better than the way marcella told you to make it. Eat this simply with some spaghetti or papardelle, maybe a bit of parmesan over the top.
