IMHO Jet's pepperoni slices would qualify as very thin, and not a lot of oiling off if memory serves. I will take note on these on the next one.
Thanks for the added information and your continuing interest and participation in this project.
What puzzles me most about the pepperoni used on Jet's pizzas is that when I look at the Jet's nutrition information at http://jetspizza.com/nutrition/category/13
and compare the nutrition data for a small square Jet's cheese pizza with a small Jet's square pepperoni pizza, the difference in weights is only 6 x 2 = 12 grams, or 0.42 ounces. Since Jet's charges extra for the pepperoni slices, I would think that they would just make a regular cheese pizza and add the pepperoni slices to it, rather than stiffing the customer by using less cheese. I did a check of three different brands of pepperoni slices in my freezer and one of them, Wilson, has a similar ingredients list for the pepperoni slices (it's almost exact, but for one ingredient). 12 grams worth of pepperoni for that brand comes to 6 slices. That is why I wondered whether possibly Jet's uses very thin pepperoni slices. That would not be unusual, because I know that companies that make pepperoni slices often offer their products in different thicknesses. Twenty slices of the Wilson brand would come to 40 grams, or 1.41 ounces; fifteen slices (based on a Jet's photo) comes to 30 grams, or 1.08 ounces. The numbers aren't much different when using the data for the other two brands of pepperoni in my freezer (Hormel and Armour).
For the record, a while back I did a Google search using the exact string of terms used to describe the Jet's pepperoni in the ingredients listing given in the Northville public school document referenced earlier in this thread. I got several hits showing that the ingredients list is a fairly garden variety one--one that is used by many makers of pizza products.
As an interesting sidenote, it looks like some of the other metro Detroit pizza operators specializing in the square Detroit-style pizza want a bigger piece of the pie. For example, I read that Cloverleaf, in addition to widening its geographical net by selling its pizzas online, wants to open 30 locations by 2018 (http://www.restaurantnews.com/cloverleaf-pizza-turns-heads-around-the-world/
) and Shield's, which sold out a while back to a couple of former owners, changed its legal name to Shield's Franchise Restaurants, L.L.C. and has expansion in mind also (http://www.shieldspizza.com/franchise.html
). By contrast, Jet's is now the 17th largest pizza operation in the country, with over 200 locations (11 are company owned) and annual sales of around $163,000,000. Buddy's has nine locations. Hmmm. The plot thickens.
