Ah well, no NP leoparding I'll have to live without. What I mainly like about NP is the shape and the amount/"layout" of the cheese, so I should be OK. (I like the sauce too, but I prefer it more seasoned/spiced than straight tomatoes).
Good to know that naan should work on steel. I probably won't have be able to give anything a go over the next few weeks but I should be getting back into pizza, baking, etc. after that. I've always wanted to try for restaurant-style naan, but of course tandoors won't work in a balcony-less apartment (unless you go for the electric variety, which I hear are not so good), so I've always wondered how far I could get without one. I just need a good recipe! (I've collected a couple, but I'm looking to replicate the naan of a certain restaurant... too bad I don't live in the same city as them anymore, and I've also heard that their quality has really gone downhill since I left.)
You've mentioned quarry tiles and firebrick. If you expect that that'll be better than cordierite (or e.g. fibrament) I'll find some and pick some up next time I rent a car. I expect Home Depot should have some unglazed terra cotta tiles, according to a thread I found by googling.
At any rate, I'll be playing with the steel plate first, and that should keep me occupied (and fat) for a while. I have yet to try a true NY pizza so I will have to keep an eye out for that too.
Thanks again Scott!
