With apologoes to ZZ Top, I suggest we collect a database, later to be analyzed, of the oven temperatures of pizzerias.
My second favorite, Gario's, in Aurora, Illinois, runs at 550 degrees, for example. Not too hot, but the crust can get crispy.
Database format? (Keep the database simple but expandable.)
Pizzaria name / nation / city / oven temperature
(Additions to the format could include type and brand of oven, type and brand of fuel, texture of crust, and so forth. And the character used to separate entries ("/" in the previous) can be changed. The character does not matter, as software can organize the data if different types of data are properly seperated and the character separating the entries remains consistent.)
Delicious investigative reporting!
