What is "onion ring"?

Onion rings are a popular fast food item that consists of a slice of onion that has been coated in a seasoned batter or breading mixture and deep-fried until crispy and golden brown. The dish is typically made using sweet onions, such as Vidalia or Walla Walla onions, which have a milder flavor than other types of onions. Onion rings can be enjoyed on their own as a snack or as a side dish with burgers, sandwiches, or other fast food items. They are often served with a variety of dipping sauces, such as ketchup, barbecue sauce, or ranch dressing, to add extra flavor and depth to the dish. They can also be made at home using different cooking methods, such as baking or air frying, to make a slightly healthier version of this classic fast food item.
