I'm currently watching a DVR recording of a Travel Channel show called "Pizza Paradises," which the info screen says first aired on 7/25/2004. I believe they originally aired two different episodes of "Pizza Paradises" within a short time frame, or possibly back-to-back, as well as a third "Pizza Paradises" episode maybe six months ago (which was horrible, by the way). Right now I have it paused on a shot showing that Giordano's bottom skin is clearly a good bit thinner than the bottom skins on my attempted Giordano's clones, the first of which is pictured in my stuffed pizza blog post
(fourth pic from the top). I can't say for sure what my thickness has been, but I've been shooting for TF=0.100 oz per square inch for the bottom skin and TF=0.60 for the top, which means I should have used 13.35 oz of dough for the bottom skin and 4.96 oz for the top skin. In total, I should have used 18.31 oz of dough for each of my stuffed pizzas (10" x 2").
Good news. I happen to have Saturday's scrap dough in the fridge, and I just weighed it. The scrap dough from one of my 10" pizzas weighs 8.8 oz, and the scrap dough from my other 10" pizza weighs 9.4 oz. Since each of Saturday's two stuffed pizzas began with a hair under 30 oz of dough, that means the total dough weight of each pizza was about 21 oz. So since I rolled the top skins noticeably thinner than the bottom skins, I estimate that my bottom skins were about TF=0.110 and my top skins were about 0.08 (which would require a little over 21 oz of dough). I'd say that's probably a very good estimate (and it did involve some pretty intricate math, which fortunately a spreadsheet calculated for me).
Recap: Based on the specs I entered in my spreadsheet, I should have used 18.31 oz of dough, but it looks like I used about 21 oz. So if my estimate for the TF I ended up using for my bottom skin is accurate (TF=0.110), I'd say I want well under TF=0.100 for each of the skins. Probably in the neighborhood of TF=0.09, which calls for a total of 19.46 oz of dough. Or maybe even a little thinner than that.
