Only in NEPA do we call it a TRAY
Whether you are a lifelong Northeastern Pennsylvania resident like myself, a transplant, or a tourist, chances are that you might have noticed that we in NEPA are spoiled with an incredible selection of high quality pizza. Have you ever been to the beach (particularly New Jersey) and said to yourself "Why the heck can't I find a decent pizza?" I certainly have, and I'll second that notion when it comes to hot wings as well. In this blog, we are concerned exclusively with pizza, and in NEPA we take great pride in our rich pizza heritage. We are so proud of that pizza culture that we even have our own term for a pizza and you may not even realize it. Here in the Northeast PA, we refer to pizzas as "TRAYS." It doesn't matter if it's an Old Forge, a Sicilian, a New York, a Chicago, or a Margarita style pizza - we call it a tray.For many, the term "tray" has always just been synonymous with pizza. You call up the local pizzeria and order "2 large trays with pepperoni" and sure enough when you get there, the pizza guy has 2 steaming hot pepperoni pizzas ready for you! They understand the vernacular, and it is rarely second guessed here in the 570. It's really part of the very fabric of the pizza scene here, but how did we come up with the name? I've asked around over the years and no one can provide a thorough historical answer on the topic, but one would surmise that the term probably originated with the creation of the Old Forge pizza which is traditionally cooked on a metal tray and served on a plastic cafeteria tray. If this is the root of the term, why don't we call french fries "cardboard containers" or hot sandwiches "aluminium foil?" OK, maybe those are a bit far fetched, but why do we call pies "pies" and not pizzas "pies?!?!"

Now before you give me the "well they call long sandwiches on a bun hoagies, grinders, subs, heroes, etc" argument so the same concept applies, I challenge you to find an alternative term for pizza besides "pie." It is no easy task! Equally as challenging is finding evidence that people outside of the area refer to pizzas as trays. I tried searching google, yahoo, bing, and ask to find references to the term and had very limited success. Is it possible that this concept is just not published online (or that no one is neurotic enough to write about it!)? Perhaps my search engine skills are not up to par, so I continued my research by interviewing people who have been to or have friends/relatives in other areas of the country to see what they call pizzas. I've got eyes and ears on the ground in Albequerque, Providence, Lincoln, Louisville, Cincinati, San Francisco, Des Moines, and San Antonio. All of my sources there tell me that pizzas are referred to as "pizzas" or "pies." They have never heard of any other terms, and certainly never refer to the pies as "trays." I have a reliable source in nearby Binghamton, NY who thought I was speaking another language when asked the question! There is evidence that some NEPA transplants in Harrisburg, Philadelphia, and Allentown to use the tray terminology, but they appear to be in the minority, which means that this term is exclusive to the northeast region of the great state of Pennsylvania.
Now I can continue to rant and expound on my ideas about the term, but when I take a step back and really think about it, how awesome is it that we as a group have our own word for a pizza? It's pretty darn cool! It's a real testament to how important the pizza industry is here in NEPA. People may look at us a little funny when we leave the area and request a tray, but deep down we know that the pizza that we get outside the area probably isn't quite as good as what we can get right here at home. So I say celebrate the term "tray" and use it every time you refer to a pizza - well, except around me - it still sounds like nails on a chalkboard to me. I'll stick with "pie", but I'm glad I'm part of an area with it's very own pizza terminology!
