Da Lian Huo Shao, or fried wheaten pancake with filling, is a pan-fried roll filled with different stuffings, including pork with fennel, pork with cabbage, lamb with green onion and multiple vegetarian options. Its origins can be traced to the time of Emperor Guangxu (1662-1722) of the Qing Dynasty. The pancakes are fried golden brown, but they remain very soft and delicious. Like dumplings, they usually go with vinegar. Beijing locals like to eat the pancakes while having a bowl of sweet and sour soup made of chicken blood and tofu.
