I learn most things by experience, and this evening taught me that it isn't a very good idea to put parchment paper under a pizza that you are going to cook on a stone on the BBQ. Wow, it was really exciting! The parchment paper immediately caught fire and melted into the pizza. The pizza also was really black on the bottom--I mean really black (think it was a combination of the heat of the stone and the ability of what Bruce would term the lowest of low grades of parchment's ability to melt into anything subjected to 600 degrees).
... that Peter Reinhart's "Sweet and Sour Onion Marmelade" is really really good. I made a sourdough, whole-wheat grilled pizza last night (no recipe, really -- I kinda just threw it together) and made the onion marmelade from American Pie.
Amazingly tasty. I plan to use it on sandwiches and, given how incredibly tasty it is, I may just make a foccacia for dinner sometime this week!
I spent a few months looking for a good grilled pizza recipe awhile back. I eventually stumbled upon a version by Americas Test Kitchen, which actually turned out pretty darn good. It took me awhile to convince my wife and kids that I could make a pizza on my gas grill, but that didn't stop them from eating it. :) Actually, everybody I've mentioned it to is skeptical about it. Not sure if they doubt my skills or the concept in general. It's a fairly straight forward recipe, but there are a couple things that can easily be modified for your tastes.
