If you ever go to a genuine Italian place and have a great sauce, the secret is Anchovies.
Yup, anchovies lend tremendous depth to red sauce/marinara. As far as pizza, maybe it’s a northern US thing/Italian thing. Even up there I think it’s pretty rare, though. I never ordered it from a chain pizza joint, I’m surprised they even sell it. Although I do think the chain brands have gotten a little better in the last decade or so.
