Chicago styles pizza is distinguished by a number of different factors. For example, Chicago style pizza is a particularly deep dish style of pie. In this regard, Chicago style pizza contains a base or a crust that is formed up the sides of a deep dish pan. (It is cooked in a pan and not directly on the bricks or other baking surface.) Another of the unique features of Chicago style pizza rests in the fact that this type of pizza actually reverses the order of the ingredients. When it comes to the more common combination and ordering of toppings on Chicago style pizza, the base or crust (obviously) remains on the bottom. However, from there the cheese is placed on the base or crust. This is followed by “filling” or toppings. (There can be a variety of other toppings used on a Chicago style pizza to taste.) The sauce (which normally is spread directly on the base or crust) ends up being placed on top of everything else that is placed the Chicago style pizza. There is another version of the Chicago style pizza this sometimes is referred to as a stuffed pizza. This variation of the Chicago style pizza utilizes two layers of crust, with sauce and toppings or filling on both. There are a variety of variations on the deep dish pizza theme in this day and age. Generally, it is agreed that the invention of the deep dish pizza occurred in the United States. With that said, the deep dish pizzas that are seen in different locations today actually transcend a single ethnic group. Most pizza historians attribute the actual invention of the first deep dish pizza to Ike Sewell and Ric Riccardo. It is believed that the first deep dish pizza was served at the Pizzeria Uno bistro in 1943. This iconic pizzaria is still in operation today. When all is said and done, there are many different types of pizzas available today. Moreover, people who consider themselves connoisseurs of pizza believe that the development of new versions of the pizza pie hardly is at an end. Indeed, with each passing year, there seems to be new, tasty additions to the more universal family of pizzas. In the end, it seems that the types of pizzas that will be seen in the future is only confined by the imagination of people the world over.
