Roujiamo

Roujiamo or rougamo (Simplified Chinese: 肉夹馍; Traditional Chinese: 肉夾饃; Pinyin: ròujiāmó / ròugāmó; lit. “meat sandwiched in mo”) is a Shaanxi street food of chopped or shredded stewed meat packed into a wheat flatbread (馍, mó). It is eaten nationwide as a portable snack and is frequently sold in combo with Liangpi. English marketing sometimes calls it a “Chinese hamburger”; that comparison is a modern nickname, not a historical claim that the sandwich invented the hamburger form.

Characteristics

A classic Xi’an-style serving uses lazhi pork (腊汁肉)—pork braised long in a richly seasoned, fat-capped stock until soft—chopped or hand-pulled and moistened with braising juices, then stuffed into a split baijimo (白吉馍). Good baijimo should be crisp outside and soft inside when freshly baked; clay-oven or hanging-oven versions differ sharply from pan-fried breads that only approximate the crust. The sandwich is savory, lightly spiced, and meant to be eaten hot and handheld.

Regional grammar varies. Tongguan roujiamo is known for a layered, blistered, expandable mo eaten hot, often with cooler meat so the contrast of temperatures stays sharp. Baoji (western Shaanxi) styles may use minced meat sauce (臊子) with a vinegar note rather than lazhi shreds. Hui and other Muslim stalls commonly substitute beef or lamb seasoned with cumin and pepper instead of pork. Outside Shaanxi, some vendors roast meat in vertical-spit styles closer to modern kebab carving; those are local adaptations, not the Xi’an lazhi baseline.

Ingredients (overview)

Encyclopedic overview only: wheat yeasted flatbread (baijimo or regional mo); pork, beef, or lamb cooked as lazhi stew or minced sauce; ginger, scallion, and a spice set that may include star anise, cassia, and Sichuan peppercorns for pork versions. Optional green pepper or other vegetable add-ins appear in some shops. No recipe steps here.

History and culture

Roujiamo sits in Guanzhong snack speech where “X-夹馍” simply means a filled mo; lazhi-meat versions became the nationally famous Shaanxi export. Food essays sometimes link baijimo to Bingzhou / Beiji town (today’s Binzhou area) place-name lore along old Shaanxi–Gansu routes—useful etymology folklore for the bread name, still not a sealed invention date for the modern street SKU.

Claims that roujiamo is “the world’s oldest hamburger,” stretching the mo to Qin or Zhou antiquity, are popular tourism talk. Stuffing meat in bread is a worldwide pattern with many parallel histories; treat extreme antiquity marketing as disputed / folk, and keep the documented frame to Shaanxi street-food culture of the modern and late-imperial snack trade.

Easy-mix warnings: do not confuse baijimo used for lazhi pork with the denser torn mo of Yangrou Paomo, even when both are sold on the same Xi’an street. Do not merge Tongguan’s layered crisp mo with soft pan “hamburger bun” copies sold far from Shaanxi. Green-pepper add-ins are a widely accepted shop option, not a purity test.

In contemporary China the sandwich is a migrant-vendor classic, a Xi’an night-market staple, and a packaged brand product. On this wiki it groups with Liangpi, Yangrou Paomo, and Biangbiang Noodles as Shaanxi snack-map neighbors rather than with Cantonese roast-meat bao.

Serving and variations

Sold as a snack or light meal, often with a side of Liangpi. Meat choices follow shop identity (pork lazhi, beef, lamb, chicken). Bread quality—oven-baked versus griddle—changes the sandwich as much as the filling. Keep distinct from Donkey Burger (Hebei) and from generic “Chinese hamburger” fast-food copies that use burger buns.
