Extra-Numbing Wontons (老麻抄手) are Sichuan and Chongqing's most peppercorn-forward wonton tradition, built around a graded numbing scale that runs from barely numb to extreme. At the lao ma level — the heavy end — thin-skinned pork wontons are placed in a bowl pre-loaded with Sichuan peppercorn powder, chili oil, soy sauce, and garlic, then flooded with scalding bone broth that fuses the seasonings on contact and releases the peppercorn's numbing compounds through the heat. The numbing spreads across the lips and tongue before the chili heat arrives, and lingers for several minutes after the last wonton. The style is most closely associated with Chongqing's street food culture, particularly the Fuling district, where lao ma wonton shops proliferated from the late twentieth century onward.
Chaoshou is the Sichuan and Chongqing name for wontons, derived from the wrapping gesture: a square wrapper is folded diagonally into a triangle, then its two short tips are pressed inward and overlapped at center, mimicking arms folded across the chest. Wontons appear in Chinese texts as early as the Han dynasty and spread southward and westward through the Tang and Song periods into distinct regional forms. The Sichuan variant's defining move was foregrounding the seasoning bowl over the broth — trading clear stock for a base of chili oil, Sichuan peppercorn, and garlic. The lao ma style extends that logic further, returning hot bone broth to the bowl as the activating medium for a heavy peppercorn charge. The numbing-grade system — wei ma (faint), zhong ma (medium), lao ma (heavy), te ma (extreme) — is a shop convention rather than a dish with a named inventor; the style is most closely associated with Chongqing's Fuling district, where lao ma wonton shops grew steadily through the late twentieth and early twenty-first centuries.
The bowl arrives wreathed in the scent of chili oil and roasted Sichuan peppercorn. The broth surface is brick-orange, with peppercorn flecks not yet fully dissolved. First wonton: numbing spreads from the tip of the tongue outward in a low, even buzz — broader and more persistent than in a standard red-oil wonton. Chili heat follows a beat behind; bone broth grounds the bowl with deep, gelatinous savory weight. The filling is springy and moist. By the third wonton the mouth buzzes evenly; after the last, the lips stay numb for several minutes, and everything tastes faintly electrified.
The defining technique is chong wan (flooding the bowl): Sichuan peppercorn powder, chili oil, soy sauce, and garlic are pre-measured into the bowl; scalding bone broth is then poured in from a height, simultaneously dissolving the seasonings and releasing the peppercorn's numbing compounds through the heat. These compounds — polyunsaturated fatty acid amides led by hydroxy-alpha-sanshool — act on the mouth's mechanoreceptors rather than heat-sensing receptors, producing a low-frequency buzz rather than burning. The bone broth's dissolved fats serve as a natural carrier, distributing the fat-soluble compounds evenly through the liquid. At the lao ma grade, peppercorn is used at several times the quantity of standard preparations, pushing the mechanoreceptor activation to its ceiling. A small addition of food-grade lye in the wonton dough raises alkalinity and tightens gluten cross-links so the wrappers stay elastic and bite-resistant after simmering, rather than turning soft and gummy in the broth.
Variations
Most Chongqing lao ma shops grade the dish into four or five levels: barely numb (wei ma), medium (zhong ma), lao ma (the namesake), and extreme (te ma). A clear-broth version omits chili oil entirely while keeping the heavy peppercorn charge, delivering pure numbing in a pale stock without the red-oil heat — better suited to those who want the buzz without the fire. Chengdu's classical chaoshou tradition runs differently: red-oil wontons use a sauce-only base with sesame paste and far less bone broth, producing a richer, drier preparation where the sauce coats each skin rather than pooling beneath it. The filling is almost universally minced pork; upscale versions add fresh shrimp.

How it's made
6 steps · 55 min
- 15 min
Dissolve a small pinch of food-grade lye (or baking soda) in the water. Combine with wheat flour and knead to a smooth, firm dough. Cover with a damp cloth and rest 30 minutes.
- 210 min
Roll the rested dough on a lightly floured surface to about 1 mm thickness. Cut into 8–9 cm squares. Dust between layers to prevent sticking. (Store-bought thin wonton skins work well as a substitute.)
- 310 min
Combine ground pork with minced ginger, soy sauce, sesame oil, and a pinch of white pepper. Beat vigorously while adding iced water tablespoon by tablespoon until the mixture turns pale and sticky. Chill 15 minutes.
Watch outBeat the filling one direction, adding iced water spoon by spoon, until it turns pale and sticky — that's when it's aerated enough to stay juicy.
- 415 min
Place a wonton skin flat on the work surface. Spoon a small mound of filling at the center. Fold diagonally into a right triangle, pressing the edges firmly to seal. Press the two short tips of the long side inward and overlap them at center — the crossed-arm chaoshou fold.
- 55 min
For each serving bowl, add in order: a generous measure of ground Sichuan peppercorn (at the lao ma grade, use at least twice the amount of a standard red-oil wonton), chili oil, soy sauce, garlic paste, a dash of vinegar, and salt to taste. Stir briefly.
- 610 min
Bring a large pot of water to a rolling boil; cook wontons in batches until they float and the skins turn translucent, 3–4 minutes. In a separate pot, bring bone broth to a vigorous boil. Ladle scalding broth into the prepared spice bowls — the force activates the peppercorn's aromatics. Transfer cooked wontons into the broth with a slotted spoon. Scatter sliced scallion and serve immediately.
Watch outPour the scalding broth into the spice bowl from a height so the force hits the peppercorn and releases its numbing aroma — lukewarm broth leaves it flat.
