Thanks to a sourdough starter from gastro gnome (who got it from thaiobsessed?), I've been playing around in the kitchen with pizza again. I'd never used a starter before, so I went with
Jeff Varasano's recipe/technique, which calls for a starter, and went from there. My first attempt, using 00 flour, was a total failure. Horrible. I switched to King Arthur bread flour and a longer cold ferment. Good, but not great. The flavor was good, but not enough oven spring. I left a couple of balls to cold ferment even longer (4 days), then allowed them a longer rise on the counter, and jacked the heat in my broiler (~825 surface temp on my tiles). Success.

Sliced mozzarella on bottom, simple crushed tomato sauce on top, and a couple of anchovies
(yes, this was a small pizza done with a half-sized ball of dough. I started doing them smaller so I could experiment more without ending up with too much pizza)Nice charring on the bottom (forgot to snap a pic), nice bubbly spring, pleasing chew, and well-developed flavor. I'm thrilled, and looking forward to more experimentation.
