"Pecking" Duck or "Peeking" Duck?

I was at a wedding dinner last week. Before we were allowed into the ballroom for dinner, we were served cocktails, which are usually just a variety of cold drinks and light alcohol. I was therefore pleasantly surprised when a waiter bearing a heavy tray of little rolls came up to me and asked if I would like something to eat. Normally, I would decline, but he said, "It's Peking Duck." Since this is not your usual hors d'oeuvre, I decided to try a piece. Delicious! I stopped at one piece or that would have been my dinner instead of the eight-course meal to follow. That little snack got me thinking. I have always heard this dish pronounced as "Peeking" Duck. The waiter pronounced it as such. However, I have heard westerners say "Pecking" Duck. Hmmm ... so which one is correct? According to this site, "Peeking" is the correct pronunciation. I thought so. Of course, when referring to the capital of China, "Peking" is no longer used. We call it Beijing (北京). I suppose the old name smacks of western colonialism. I much prefer the new name. Let's call a city the way the locals do. But as for the duck dish, it will probably remain as Peking Duck for a long time to come. Bon Apetit! Note: If you are in Beijing and want to savour authentic Peking Duck, you will have to order it by its Chinese name: Beijing ya (北京鸭).
