Following the Ottomann defeat, according to some accounts, Austrian bakers wanted to celebrate their victory by creating a pastry that would symbolize the crescent moon that appears on the Turkish flag. The kipferl — the German word for "crescent" — became that symbol. For Austrians, eating a kipferl was a culinary re-enactment of victory over the Turks — eating their enemy.
It is a favorite at the coffee club which I attend as often as possible at Pain Perdu. I have sent the link to all the club members.
I do like learning trivia history like this. Like how the phrase "saved by the bell" came into being. In days past folks used to be buried alive, apparently with some frequency. So in case a person being buried might not actually be dead a string was attached to a bell that was hung on the headstone, and run down into the casket. This problem also gave us the :"graveyard shift" as a person was hired just to sit in the graveyard and listen for the bell for a couple of nights after the funeral.
