Peking Duck of course!!!!! It's so amazing! I got to have it both times I visited Beijing and I stuffed myself until my stomach hurt. I literally had a belly for the rest of the trip.
Peking Duck (Peking was the old way to say Beijing) has been around since the Ming Dynasty (1368–1644) and is considered the national dish of China. That is not to say that people haven't been roasting duck in ovens since before then. Special ducks are bred to be cooked this way. What's special about this dish is that the skin is very thin and crispy and it's often eaten in a pancake with scallions and sauce.
In the restaurants the cooks will cut the duck in front of you as part of a show.
Here's the pancake with scallions and sauce. It looks like a crepe, yes...and my focus was way off.
Thankfully there are no pictures taken of me eating this, because I'm really fanatical about my Peking duck. If you ever get a chance to try it (even if it's not in China) please do!
