pmad, you said it ALL!
Even more specific: that is North County St. Louis pizza! I think this is much more superior to even the other pizzerias around the metro area. I personally feel that Angelo's is superior to all in North County. Halls Ferry Inn came from Ponticello's, which was awesome. As a matter of fact, all of the North County pizzerias originated from Ponticello's.
I actually studied with Angelo's on their dough. There are two secrets there: the yeast and the rise time.
In regards to the sauce, respectfully, I disagree. If the sauce is heated, and in my opinion, it should be, it should always be low and covered. That's why you see places like Faraci's, Pirrone's, Angelo's, and Fratelli's using covered steam kettles. Both heating time and temperature affect flavor loss, unless done in the right way.
Is your sauce based on a particular favorite pizzeria?
