Curiosity - Subway Toasted Sandwiches
Not really a fan, but my teenager loves them, so we go there on occassion. The other day I noticed that the person putting the sandwich together placed the split sandwich on a piece of paper before toasting it. The sandwich came out hot and slightly browned, but the paper wasn't burned at all. I asked what type of toaster and paper were used, because I couldn't understand why the paper wasn't burned even slightly, but couldn't get a meaningful answer out of the Subway sandwich maker.
Does anyone know why the paper doesn't burn? (Yes, these things sometimes just keep nagging at me).
Never having had a toasted Subway sandwich(no...once in a maroon moon when I have a Subway "Italian" sub I do not want it toasted, thank you franchise worker)and not understanding the toasted sandwich craze that's infected Subway, Quizno's, Potbelly, et al(to the extent that you read CH'rs criticizing certain sub shops because they don't toast their subs...hellooo!)...
: I assume they're using parchment paper...parchment paper withstands very high temperatures w/o browning...it degrades during "long" cooking, but a quick pass through a Subway toaster wouldn't do a thing to it.
Subway's broiler system is at a very high heat, but for such a short period of time that I don't think parchment has a chance to burn. I've made homemade pizzas that I place on semolina-dusted parchment and the parchment directly on the shelving in a 500 degree oven for 10-15 minutes; that's where you'll definitely see some blackening.
