In Reply 220, I alluded to weight factors associated with an entire small Jet's square cheese pizza. The reason I mentioned that was because pizza weight data given in nutrition information isn't always helpful. It is usually most helpful when used in conjunction with other information, such as the ingredients used to make the pizza and information such as the dough ball weight, the amount of cheese used, the amount of sauce used, the amount of weight loss during baking, etc.
To be more specific, in Jet's case the nutrition information given at its website at http://jetspizza.com/nutrition/category/13
says that a single slice of a small square cheese pizza weighs 114 grams. So, for six slices, the weight of the entire pizza is 684 grams. There is an asterisk Next to the words Serving Grams that, on the pdf copy of the nutrition information, says that one ounce is 28.35 grams. So, 684 grams translates into a weight for the entire pizza of 24.13 ounces.
During the course of this thread, we had two members, PizzaHog and Tommy Nott, who actually purchased pizzas from Jet's and weighed them. In PizzaHog's case, he purchased a small cheese and pepperoni pizza and, after removing the pepperoni slices, weighed the rest of the pizza. The weight he reported was 685 grams, or 24.16 ounces, or almost exactly as reported by Jet's for a small square cheese pizza. However, PizzaHog, who had purchased pizzas from Jet's for many years and was very familiar with what he was getting, reported that the worker who made his pizza used a heavy hand for the cheese, sauce and pepperoni. He also indicated that he did not see much in the way of fat rendered from the pepperoni during baking.
Subsequently, Tommy Nott purchased two small square pizzas from Jet's and weighed them shortly after purchase. In both cases, his weights were about 21 ounces, or losses of around three ounces when compared against the Jet's weight information. It was because of Tommy's experience with Jet's that I inquired at the FDA as to what recourses one had when a pizza sold by a pizzeria weighed less than its own nutrition information said. I was told that if the pizza was a frozen pizza (and presumably with a Nutrition Facts label as typically shown on the pizza box), then one could file a complaint with the FDA. But if the pizza was from a pizzeria, the recourse would be to go the pizzeria and complain.
I eventually came to the conclusion that Jet's most likely hired a specialist to create the Jet's nutrition information and, for this purpose, the specialist worked from a basic dough recipe (before cooking) along with information, including nutrition information, from the suppliers of the ingredients used to make the Jet's pizza, such as the flour, cheese, tomatoes, seasonings, etc. This was not an approach that was new to me. Some time ago, when I was trying to reverse engineer and clone the pizza dough used by the Papa Gino's chain in the Northeast, I had an exchange with them after I had purchased a pizza that weighed quite a bit less than what was stated in the PG nutrition information. The post where I reported on the matter is Reply 101 at http://www.pizzamaking.com/forum/index.php?topic=8167.msg75915;topicseen#msg75915
. Based on the foregoing, I recently sent an email to Jet's asking if their nutrition information for their pizzas is for baked or unbaked pizzas. If an answer is forthcoming, that might help us determine how much cheese and sauce (seasoned) is used with a 20-ounce dough ball to make a clone of a small Jet's square cheese pizza.
