How to: perfect Neapolitan pizza at home SEP 16 2010
Over at Serious Eats, Kenji Lopez-Alt assures us that while you can't make restaurant-quality Neapolitan pizza at home, you can come damn close. Best thing is, his technique doesn't involve lining your oven with bricks and is actually as easy as making regular pizza at home.
After cooking for around a minute and a half, the bottom crust achieved the perfect degree of char-even better than what I was getting on the stone. Interestingly enough, the pan was actually cooler than the stone I was using, maxing out at around 450 degrees. So how does a 450 degree pan brown better and faster than a 550 degree stone? It's a matter of heat capacity and density.
The heat capacity of a material is directly related to the amount of energy that a given mass of material holds at a given temperature. Even though stone has almost twice the heat capacity than steel (.2 kcal/kg C vs. .1 kcal/kg C), it loses in two ways: it is far less dense than steel, and it has a much lower rate of heat conduction than steel. The pizza cooking in a skillet is not just getting energy from the pan-it's getting energy from the burner below the pan as it gets rapidly conducted through the metal.
It's a clear demonstration of how when cooking foods, what matters it the amount of energy transferred, not just the temperature you cook at. The two are often directly related, but not always.
I have said it before but will repeat: I love Kenji's nerdiness about the science combined with the ability to come up with the solution that's easiest for non-nerds to appreciate and implement. It is a rare and wonderful thing to observe.
