Detroit style pizza
Pizza at home is decided by two variables the baker controls — what is in the dough and how much heat reaches it — and almost everything else is decoration. Every piece isolates one of those variables, states the numbers, and tests changes against a domestic oven rather than a deck oven the reader will never own. Toppings are treated as a load on the bake, not as a subject in themselves.
