We said that every state, whether they like it or not, has its own iconic food. For New Mexico its the green chile, for Oklahoma its everything that’s fried (and the deep-fried gummy bears) and for Illinois its the deep-dish pizza that originated in Chicago. While most people from Illinois will argue they don’t touch this stuff and they’re better than that, it’s still considered a state pride.
Properly named, the deep-dish pizza is a pizza made inside a deep dish that allows for more cheese, more sauce, and basically more of everything. It constitutes a great part of the tourist attractions in Chicago, and after their notoriously cold weather, and their love for the Cubs, this is what Illinois is most known for around the U.S.
