I only used two small cans and the flavor is pretty mild. Last time I made this I just used one can and you couldn't taste them at all really. I like that they're incorporated into the dish .. after being diced up and cooked down they really mellow out and add a nice salty flavor (I didn't even have to add any salt to the pan). But yeah, whole anchovies on a pizza? I'm not a fan of that really.
