Friend of Slice Pizzablogger uses a word from the pizza-crit lexicon that I've never heard before: leopard spotting, obviously a reference to the little blisters of charred material along the pizza's end crust (or cornicione).
Usage: "I think the quattro formaggio looks very lame, although it has more leopard spotting on the outer edge of the cornicione than the other pictures, which is what I personally prefer."
Pizzablogger picked up the term from Paulie Gee.
But I'm also wondering if you couldn't apply leopard spotting to what you see in an upskirt shot as well:
And maybe even to the little almost-caramelized bits of slightly burnt cheese that I have a fondness for?
