Pizzas’ popularity in the US is unflagging. There are an estimated 70,000 pizzerias in the country and the combined annual sales of the fast food is worth $38 billion. On average, 3 billion pizzas are sold a year. This particular food favorite dates back to at least AD 997 in Gaeta with the first known record of the word pizza. Pizza then spread to different parts of Central and Southern Italy. The early form of pizza was probably the focaccia, a flatbread known to the Romans as panis focacius, to which toppings were then added. The Romans loved fermented fish paste to season their food, so they were probably the first to apply anchovies. Of course, many countries had flat bread and what they did with it in terms of laying on favorite foods, is lost in antiquity.
Colorado, like all other states, has numerous pizzerias, and, in keeping with all other food outlets, hygiene is a highly-regulated top priority. A successful pizzeria brew pub recently opened another one in Colorado Springs.
