“A baked flatbread (mo) split open and stuffed with pork belly slow-braised for hours in a spiced broth of star anise, cinnamon, cumin and more than 20 aromatics.”
The mo is baked in a clay oven and arrives with a crisp exterior and a soft interior — the split absorbs the braising liquid from the pork.
What to Expect
At the Muslim Quarter in Xi'an the rou jia mo vendor chops the braised pork directly on a board and stuffs it into the bread with a ladle of braising liquid. The bread is immediately soaked through.
Why Try It
Rou jia mo tells you about Xi'an's Silk Road history — the cumin and caraway in the broth are Central Asian; the pork is Chinese.
Insider Tips
- Order from stalls with the highest turnover — freshly braised pork versus reheated is a significant difference.
- Xi'an's Huimin Street night market is the best location.
- Ask for extra braising liquid in the bread.
