On a small round white plate rests a golden baked baijimo flatbread, split open through the middle and filled with large strips and chunks of braised pork, including pale fatty pieces, all glistening with gravy.
Shaobing, griddle bread, guokui, naan, spring pancakes and other wheat flatbreads.
Rou jia mo is a Shaanxi snack of chopped, slow-braised spiced pork (lazhirou) stuffed into a split baijimo flatbread; the name is a playful Xi'an inversion of the phrase for bread with meat. The meat's lineage can be traced in texts of the Zhou and Tang periods. Fan Bingren came to Xi'an in 1904, sold braised pork on the streets, and his son put the meat in bread. This account is considered more believable than others, but historical evidence remains limited: Mo Zuodong's March 28, 2020 essay cites the Xi'an city gazetteer for meat in baijimo without giving a year, and the gazetteer itself was not consulted.
What
Rou jia mo is a Shaanxi snack of slow-braised, chopped spiced pork (lazhirou) stuffed into a split baijimo flatbread. The baked bread has a crisp crust, a soft inside, and an iron ring, chrysanthemum center, and tiger back appearance (2026 description).1,4
When
The meat's lineage can be traced in texts of the Zhou and Tang periods. Fan Bingren came to Xi'an in 1904, sold braised pork on the streets, and his son put the meat in bread. Historical evidence remains limited: Mo Zuodong's March 28, 2020 essay cites the Xi'an city gazetteer for meat in baijimo without giving a year, but the gazetteer itself was not consulted; the listed sources provide no documentary support for an inheritor's claim in a January 2024 report that the snack has over 2000 years of history in Xi'an.2,3
Where
Shaanxi, centered on Xi'an; Tongguan and the Xifu area around Baoji have their own versions. Its county of origin remains unsettled.1,4
How
In 2 home recipes, skin-on pork belly is blanched, then pressure-cooked for about 30 minutes with rock sugar, soy sauce, and spices such as star anise and cinnamon. The liquid is reduced, and the meat is chopped with it. The bread dough is raised, set in a dry pan, and baked at 180 degrees Celsius until crisp.5,6
Why
One origin account holds that men carrying luggage wanted a meal they could eat with one hand, so they put meat in bread. The meat and bread each have older, separate histories. A 2015 explanation presents the name as a playful Xi'an inversion of the phrase for bread with meat.3,7
Impact and influence
In 2024, Xi'an had tens of thousands of rou jia mo shops. Rou jia mo is one of Xi'an's traditional snacks; in 2015, the city drafted a local standard for traditional snacks.2,7
According to the 2020 essay on The Paper, Fan Bingren came to Xi'an in 1904 and sold braised pork on the streets, and his son tucked the meat into bread so that the men carrying luggage could eat with one hand. The essay judges this account more believable than the other origin tales.
Told in: A Xi'an account, told in Mo Zuodong's essay on The Paper of 28 March 2020; the Xi'an city gazetteer it cites was not opened.
A Tang Emperor at Tongguan
One story ties the snack to the Tang emperor Li Shimin and says he discovered it at Tongguan. The essay on The Paper calls stories of this kind far-fetched, so it is recorded here as a tale and nothing more.
Told in: A tale from the Tongguan area, relayed with doubt in the 2020 essay on The Paper. No old text that records the story was found.
This is a simplified home version, not the traditional restaurant method.
In the shops the meat is stewed slowly in a big pot of old broth. This is the simpler way I make it at home: pork belly is cooked in a pressure cooker and then reduced in an open pot, and the bread is set in a pan and finished in the oven. The amounts and timings below are my own choices at home, adapted from two published recipes.
Ingredients
All-purpose flour 300 g
Warm water 160 ml
Instant yeast 5 g
Baking powder 2 g
Salt, for the dough 2 g
Skin-on pork belly 500 g
Ginger slices 3 slices
Scallions 2 stalks
Star anise 2 pods
Cinnamon bark 1 small piece
Bay leaf 1 leaf
Sichuan peppercorns 1 teaspoon
Rock sugar 10 g
Light soy sauce 15 ml
Dark soy sauce 10 ml
Cooking wine 15 ml
Salt, for the pork 5 g
Fresh green chili (optional) 1
Steps
Mix the flour, yeast, baking powder and salt, add 160 ml of warm water and knead to a smooth dough. Cover and let it rise. I give it about an hour, until it has roughly doubled.
Wash the pork belly, cut it into four large pieces, start it in cold water, and blanch it for about 3 minutes after the water boils. Lift it out and rinse.
Put the pork in a pressure cooker with the ginger, scallions, star anise, cinnamon, bay leaf, Sichuan peppercorns, rock sugar, both soy sauces and the wine, and add water to just cover the meat. Cook under pressure for about 30 minutes, turn off the heat, and wait for the pressure to release by itself before opening; never force the lid.
Open the lid, add the salt and simmer uncovered over low heat. I usually go for twenty to thirty minutes, until a chopstick slides in easily and the liquid is thick and glossy. The pork must be tender all the way through, with no raw part when cut.
Divide the dough into 5 pieces, roll each into a rope, coil it like a snail and flatten it into a disc about 1 cm thick. Cover and rest for 10 minutes.
Cook the discs in a dry pan over low heat, a few minutes on each side, until golden spots appear and they hold their shape. Then bake them at 180 degrees Celsius. I usually bake 8 to 10 minutes, until the surface is golden and crisp.
While the pork is warm, chop it together with some of the cooking liquid, and mix in chopped green chili if you like. Split each flatbread through the side without cutting it apart, fill it with the meat and spoon on a little of the liquid.
Tips
Chop the meat together with some of its liquid so the filling does not dry out inside the bread.
Follow the instructions for your own pressure cooker, do not use too little water, and wait for the pressure to go before you open it.
