Don’t let onions make you cry today; celebrate them instead! June 22 is National Onion Rings Day, an annual holiday in the U.S. honoring one of America’s tastiest fast-food creations.

No one knows the exact origins of the onion ring, but a recipe is thought to have appeared first in an 1802 cookbook by John Mollard called The Art of Cookery Made Easy and Refined. It called for half-inch-wide rings battered in cheese, flour, cream, eggs, and salt and pepper, fried in lard, and dipped in a sauce of butter and mustard. Some food historians claim that the onion ring was born and popularized in the early 1920s with the establishment of the drive-in Pig Stand restaurant chain in Texas. Today there are hundreds of recipes for the famously deep-fried delicacy.
