Pizza
Pizza demonstrates extraordinary evolutionary flexibility. The base template of dough, sauce, and cheese has spawned countless regional variations: the thin crusts of New York, the deep dishes of Chicago, the dessert pizzas of suburban chains, the vegan alternatives demanded by contemporary dietary fashion. Toppings range from the traditional mozzarella and basil to the controversial pineapple, from anchovies to artichoke hearts. Gluten-free bases accommodate the intolerant. Cauliflower crusts appease the carbohydrate-averse. Pizza bends to accommodate every preference whilst maintaining its essential identity.
