As I write this post, I'm sitting in the study at my friend's home in Belfast, looking out the French windows to his back yard. His dad is busy stoking the flames of a wood-fired stone pizza oven that he built with his own hands. This is probably the best possible way to enjoy pizza: real fire, close friends and family, everything hand-made. But I'm usually not this lucky. My own best pizzas are made on my little 80 square-foot deck on the 17th floor of a Manhattan apartment. If you're like me and your access to stone ovens is limited, the grill is your best bet for making crisp-on-the-outside, soft-and-airy-on-the-inside pizza. It's the only heat source that approaches the insanely high temperatures that are so essential to great pizza.
