Baitang Floating Noodles, a specialty of Huxian County (today's Hu Yi District of Xi'an), are served in two separate bowls: one holds translucent, alkaline hand-cut noodles so thin they are described as 'fine as thread, spinning like a lotus in the pot'; the other holds a steaming, pungent braised-pork broth loaded with day lily flowers, wood ear mushrooms, tofu puffs, tomatoes, and garlic chives. The diner picks up a few strands with chopsticks, swings them in the hot soup until evenly coated, then eats—a ritual as much as a meal. Honored as a 'Famous Chinese Snack' (中华名小吃) and listed in Xi'an's Seventh Batch of Intangible Cultural Heritage (2021).
Baitang Floating Noodles were invented in the 1940s in Huxian County town by a restaurateur named Shan Jiqing. Drawing on the long Guanzhong tradition of braised-pork broth noodles, Shan redesigned the dish so that noodles and soup were presented in separate bowls, allowing the diner to control the soup-to-noodle ratio with every bite. The innovation proved so popular that his family refined the technique across three generations, developing two signature techniques: adding salt and food-grade baking soda to the dough ('和面加盐碱') for greater springiness, and aging the braised-pork broth ('臊子汤陈酿') for deeper flavor. The name 'baitang' (摆汤, literally 'to swing in soup') describes the eating gesture that defines the entire experience. In 2025, the Huxian specialty snack-making tradition—including baitang noodles—was inscribed in Xi'an's Seventh Batch of Intangible Cultural Heritage Representative Projects.
The soup arrives scalding, assertively sour and spicy with a deep pork funk; the noodles in their own bowl are cool and springy, almost naked. Each swirl in the hot broth coats the noodles just lightly—you taste the fatty, complex braised-pork essence and a bright acidic trail, but the noodle itself never goes soft. A folk rhyme captures it: 'thin as paper, fine as thread, spinning like a lotus in the pot, a single line in the bowl, silky and tender in the mouth.'
The two-bowl system solves a fundamental food-science problem: noodles submerged in hot broth continuously absorb water, their starch granules over-swelling and turning the noodle mushy within minutes. By keeping noodles separate, the diner controls contact time precisely. Each 'swing' coats only the surface—the starch film gelatinizes briefly from the heat while the noodle core stays firm. Adding baking soda to the dough raises pH to around 9-10, driving alkaline cross-linking in the gluten network that dramatically increases the noodle's resistance to heat and soaking—the same chemistry behind alkaline noodles across East Asia. The soda also reacts with wheat flavonoids to produce the characteristic pale yellow tint and a faint mineral aroma.
Variations
Vegetarian version: pork replaced by shiitake mushroom braised filling; vegetable stock replaces meat broth. Winter cured-pork version: diced cured pork (腊肉) added to the broth for a smokier, richer base note. Modern restaurant variant: a self-service broth station lets diners ladle their preferred concentration.

How it's made
8 steps · 20 min
- 130 min
Mix high-gluten wheat flour with a pinch of salt and a small amount of food-grade baking soda; gradually add water and knead into a very firm, smooth dough; cover and rest for 30 minutes
Watch outKnead in the baking soda until the dough is very firm and smooth — the alkali toughens the gluten so the noodles resist the hot broth; a slack dough gives noodles that mush instantly.
- 215 min
Roll dough as thin as possible (under 1mm) on a well-floured board; fold and cut into very fine noodle strands; dust with flour and set aside separately
- 310 min
Blanch pork belly, then dice into small cubes and stir-fry with soy sauce, aged vinegar, five-spice, and salt until richly caramelized and fragrant
- 410 min
Rehydrate wood ear mushrooms and day lily flowers; dice tofu puffs; roughly chop tomatoes; slice garlic chives and scallions into short lengths
- 520 min
Combine braised pork, mushrooms, day lily flowers, tofu puffs, and tomatoes in a pot; add chicken or pork stock and simmer for 20 minutes; adjust seasoning with aged vinegar and chili oil to achieve a pronounced sour-then-spicy layered flavor; finish with garlic chives and scallions
- 62 min
Bring a large pot of unsalted water to a full boil; cook noodles for 60-90 seconds until just done; drain and place into one large serving bowl
Watch outCook the noodles just 60-90 seconds until barely done, then keep them separate from the broth — the two-bowl trick is the whole point; a soaking noodle over-swells and turns to paste.
- 72 min
Ladle piping-hot braised-pork broth into a separate bowl; set both bowls in front of the diner
- 81 min
To eat: pick up a small pinch of noodles with chopsticks and swing them back and forth in the hot broth until evenly coated; lift and eat; repeat continuously
