Cuisine is a type of food that is cooked in a specific way based on a culture's ingredients, region, and traditions. If you're craving cannoli, a visit to Chinatown doesn't make much sense, since cheese is more characteristic of Italian cuisine.
Boiling an egg or flipping burgers on the grill is cooking. But if you want to create cuisine, you need to understand how to prepare the culinary specialties of a particular country or culture. To make Italian cuisine, for example, you'll need to chop garlic, roll out pasta dough, and simmer pots of tomato sauce. When the word "fine" is attached to cuisine, it describes the food at a fancy restaurant that will part you with a good portion of your money.
