Niang Pi
“Cold wheat-starch sheets cut into ribbons, dressed with garlic-vinegar, sesame paste, and cumin-spiked chili oil.”
The bite
Cold and slick — the sheets are gelatinous and slippery, snapping cleanly between teeth rather than chewing like noodles. The gluten pieces are spongy, soaking up dressing like a sponge holds water. Cumin in the chili oil is the giveaway flavor versus Shaanxi liangpi: warmer, more savory, Hui-Muslim in character. Eat within 20 minutes — the sheets toughen as they sit.
Where it comes from
Niang pi is the Gansu cousin of Shaanxi liangpi — both originate in northwest wheat country, both made by the wash-out method that splits flour into starch and gluten. The Gansu version runs slightly thicker, leans on cumin in the chili oil reflecting Hui-Muslim influence along the Hexi Corridor, and in some Gansu dialects appears as 镶皮. Lanzhou street vendors keep stacks of pre-cut sheets through summer, dressing each bowl on order.
What makes it work
The wash-out trick is what defines this entire family of dishes. By kneading flour-and-water under cold water, the water-insoluble gluten proteins (gliadin + glutenin) bind into the rubbery seitan ball while water-soluble starch washes away into a slurry. Steam the slurry thin and you get a translucent, gelatinous sheet; steam the gluten and you get a spongy chew. One dough, two completely different textures in one bowl — without this separation, you can't make either.

Knead 300g high-gluten flour with 150g water and 3g salt for 8 minutes into a stiff dough. Submerge in a bowl of cold water and rest 30 minutes.
- 215 min
Wash the dough in the water — squeeze and knead it under the surface so the starch leaches out into a milky liquid. Change water 4-5 times, collecting all the wash water in a tall container, until what remains in your hands is a yellow-brown elastic mass (the gluten/seitan, called 面筋).
- 35 min
Let the starch water settle 90 minutes minimum (or 2-3 hours for clarity). Pour off the clear water on top, leaving the thick starch sediment. Stir until smooth, adjust consistency to single-cream thickness.
- 425 min
Steam the gluten ball whole for 25 minutes until puffed and spongy. Cool, then tear into bite-sized pieces.

Brush a flat metal pan with oil, ladle in 80ml starch slurry to coat the bottom in a 2mm layer, and float the pan in a wok of boiling water. Cover; the slurry sets translucent in 90 seconds. Lift the pan into cold water, peel off the sheet, brush with oil, and stack. Repeat for all batter, then cut sheets into 1.5cm ribbons.
- 63 min
Pile ribbons in a bowl with gluten pieces and blanched mung-bean sprouts. Dress with 2 tablespoons garlic-water (smashed garlic steeped in cold boiled water), 1 tablespoon black vinegar, 1 teaspoon light soy, 1 tablespoon sesame paste loosened with water, 2 tablespoons cumin-chili oil, and a pinch of salt. Toss at the table.
