What is onion ring? How to use in English

The term "onion ring" refers to a popularfried snack made from thinly sliced onion strips that are coated in batter or breadcrumbs and then fried until crispy. The origin of this name is believed to have come from the ring-like shape formed by the onion slices when they are laid out in a circle before being cooked. This circular shape also resembles the outer layer or "ring" of an onion, which is often discarded before cooking. However, the exact origin of the word "onion ring" is a bit unclear. Some sources suggest that the term dates back to the early 1900s, while others say it originated in the 1960s. One theory is that the dish was first introduced in Southern U.S. Cajun and Creole cuisine, where it was called "onion blossoms" or "Cracker onions." In the 1970s, a popular chain restaurant called Arby's added deep-fried onion rings to their menu, and the dish quickly gained popularity across the U.S. Today, it's a common item on menus in fast-food restaurants, pubs, and fine dining establishments alike. In many cultures, onion rings are often enjoyed as a snack, side dish, or appetizer. They can also be prepared using various cooking techniques, such as baking, grilling, or air frying, depending on preference. Regardless of how they're cooked, onion rings are a beloved comfort food that continues to delight foodies around the world.
