It’s National Croissant Day! Although it is most likely just a myth, the history of the croissant is a colorful tale full of adventure. In 1683, the Turkish Empire laid siege on Vienna, Austria. The Turks made several attempts to enter the city by force, but were unsuccessful, so decided to dig an underground tunnel. The bakers of Vienna, who worked in the basement storerooms, heard the sound of digging and alerted the army.
