I just found this photo I took of two identical margherita pizzas baked in different ovens at a pizzeria called 900 Degrees (RIP) in the West Village. The one on the left baked for 5 minutes and 33 seconds in a brick-lined electric deck oven, the one on the right baked for 1 minute and 24 seconds in a wood-fired brick oven.
Judging by these photos, the wood-fired pie looks way better. The lower temperature electric oven caused the fresh mozzarella to break down before the crust completely baked. You can see why pizza makers switched to low-moisture mozzarella when deck ovens became standard (besides the fact that they had a longer shelf life). The crust on the right looks more even and the cheese/sauce separation has remained intact.
But looks are only part of the picture — almost everyone on the tour that day preferred the taste of the pie on the left. BOOM!
