National Eggs Benedict Day is observed on April 16, 2022. It's a day to enjoy eggs with hollandaise sauce, english muffins and canadian bacon. Lemuel Benedict, a retired Wall Street stock broker, claimed that he had wandered into the Waldorf Hotel in 1894 and, hoping to find a cure for his morning hangover, ordered "buttered toast, poached eggs, crisp bacon, and a hooker of hollandaise."
Oscar Tschirky, the famed maître d'hôtel, was so impressed with the dish that he put it on the breakfast and luncheon menus but substituted ham for the bacon and a toasted English muffin for the toast. (With material from: Wikipedia)
