Deep-fried cheese curds are often found at carnivals and fairs, and often local non-chain fast-food restaurants and at regular restaurants and bars, as well as a few chain restaurants of local origin, such as Culver's. Deep-fried cheese curds are covered with a batter similar to one used for onion rings or breading, and placed in a deep fryer. They are sometimes served with a side of ketchup, marinara sauce, or ranch dressing. They are strongly associated with the U.S. state of Wisconsin.
