If you're asking me, yes. I paid for a very old starter yeast captured from the original Naples pizzeria.

See, thing about that is I spent all last summer in Italy and never once had a good pizza crust, and there was only one place that had decent bread. Luckily Cap D'ail was a right up the track from our home port and excellent bread was available there. I was really really disappointed with the quality of the pizza crusts.
