Step-by-step explanation:
The deep-dish pizza, a culinary staple synonymous with the Windy City, is an example of regional cuisine. This type of pizza, known for its thick crust that lines a deep pie pan, ample cheese, chunky tomato sauce, and various toppings, originated in Chicago and is a beloved dish reflective of the city's cultural heritage and culinary innovation. Unlike haute cuisine, which is associated with fine dining and complex preparations, or global cuisine, which encompasses dishes that are popular around the world, regional cuisine pertains to foods that are characteristic of a specific geographical area. In this case, the deep-dish pizza is particular to Chicago.
Opting for option 3, regional cuisine is the correct choice when classifying the type of cuisine a Chicago deep-dish pizza represents. It highlights the localized nature of the food as well as its ties to the traditions and tastes of the place it comes from. This delicious dish is a point of pride for Chicagoans and a must-try for visitors, providing a savory taste of the city's rich cultural tapestry. Therefore, when identifying the deep-dish pizza's culinary category, one should correctly term it a 3)regional cuisine.
