“Crust” makes it sound like superfluous detritus. It’s cornicione! Pizza is mostly bread, so if the bread is bad then it’s not worth eating.

Neapolitan pizza has a high hydration dough cooked at very high temp, resulting in a delightfully light cornicione filled with large air pockets. The bread is delicious enough to enjoy on its own, which is why it only needs simple toppings like uncooked San Marzano tomato and a few shreds of mozarella. IMO Italian cuisine excels at allowing high quality produce speak for themselves through its simplicity and elegance. What they’re shitting out at Papa Johns and whatever is an abomination.
