An interesting story is heard in the US about the duck. At first the cooking method for roast duck was against the state food legislation of California, therefore it was banned. To solve the problem Roast Duck was sent to California University for testing. The test results showed that Peking Duck was safe as food. What surprised others was that the Roast Duck was so delicious that the scientists in the lab ate up all the tested duck. Roast Duck had long been a best seller in Beijing restaurants.
