Luckily enough, Scalia made an appearance at Chicago-Kent College of Law in October of 2011 to expound upon his originalist pizza views.
“I do indeed like so-called ‘deep dish pizza’... It’s very tasty,” remarked Scalia. “But it should not be called ‘pizza.’ It should be called ‘a tomato pie.’ Real pizza is Neapolitan. It is thin. It is chewy and crispy, OK?”
Ward notes that this interpretation of pizza, again, makes sense given Scalia’s tradition-rooted views. In Scalia’s mind, pizza is immutable, and any American bastardization of its true form (which, again, for Scalia, is Neapolitan), is inherently not pizza.
This is the final nail in the coffin for the prosecution. For Scalia, pizza began and ended at Neapolitan-style pizza. Since deep dish pizza isn’t Neapolitan, it’s not real pizza. Case closed. Deep dish is guilty, and it is, legally, not pizza.
