I was going mainly on cholesterol numbers because the only place that cholesterol shows up in a basic cheese pizza is in animal-origin (not vegetable-origin) ingredients, in this case, the cheeses, since there is no animal fat in the dough or sauce based on the PG ingredient lists for the dough and sauce. Of course, when pepperoni is used, it will also add cholesterol because it is animal based. When I analysed the total fat content between a basic PG cheese pizza and the pepperoni and Paparoni pizzas, the numbers I came up with for the pepperoni slices for the two pepperoni pizzas seemed to line up quite well with the increased total fat numbers.
I have found that trying to reverse engineer pizzas using nutrition data is not all that easy because you are trying to use data for a baked pizza, where all kinds of transformations take place, including loss of weight, to divine what is in the unbaked pizza. In the present case, it is possible that less cheese is used for a 14" pizza than I proposed, which would help the cholesterol numbers, but if that is so then that would mean that more dough and/or sauce would have to be used to make the total numbers work out from a weight standpoint. It is also quite possible that PG is using a proprietary cheese blend formulated to their specific requirements, just as they apparently do with the flour. I have also seen instances where I wonder whether the nutrition data is even correct. I also allow for the possibility that my analysis can be wrong.
My first cut is always to try to get as close as possible to the real thing. If that works based on the feedback from the members who tried to recreate the pizzas in question, then my work is pretty much done and it is up to those who cherish the pizzas to try to bridge any gaps or to make changes to improve the pizzas. However, in my experience, people seem to be more interested in recreating the product--usually for nostalgic reasons--rather than improving it.
BTW, I zeroed in on Cabot only because of its proximity to the PG footprint with its stores.
