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.

Brush up on your culinary expertise by checking out some of the science behind frying foods like onion rings, and learn more about the different types of onions and other vegetables of the same family. And don’t forget to enjoy the holiday by ditching your diet and getting your grub on!
