deviled eggs are still very popular applications of this culinary idiom.
Around 1868, the William Underwood Company (which was known originally for its mustard products, began experimenting with a new product created from ground ham blended with special seasonings. The process they dubbed "deviling," for cooking and preparing the ham, was new. Soon thereafter, the "Underwood devil" became synonymous with the processed ham product, and today the Underwood devil is the oldest existing trademark still in use in the United States.
