Soybean starch batter pressed through a perforated ladle into boiling water, forming pale jade shapes that curl like small fish. Chilled in ice water, then dressed with black vinegar, chili oil, and garlic—Zhangye's quintessential summer street snack, cooling and bracingly sour.
A generations-old street snack of Zhangye in the Hexi Corridor, sold by itinerant vendors with a distinctive call that echoed through the alleys for decades. The dish draws on the region's abundant soybean cultivation and the northwest Chinese tradition of pressed starch noodles, adapted here for summer cooling.
Slippery and cool against the tongue, with a faint elastic chew, followed by a sharp vinegar-and-chili kick that cuts through the summer heat.
Soybean starch gelatinizes at around 65–72°C: amylose chains unfold and absorb water to form a translucent gel. Pressing the hot gel through small holes while it is still fluid creates the fish silhouette; immersion in boiling water locks the shape in seconds. Chilling the cooked pieces triggers starch retrogradation—amylose chains re-associate into ordered crystalline regions—firming the noodle and giving it the characteristic springy, non-sticky bite. Acetic acid in the vinegar dressing lowers the surface charge on the gel, keeping pieces separate and slippery.
Variations
A red-bean version tints the batter pink by blending in cooked red bean paste. Some vendors blend soybean starch with fava bean starch for a denser bite. A winter hot version serves the noodles in lamb bone broth instead of cold vinegar dressing.

How it's made
7 steps · 20 min
- 110 min
Whisk soybean starch into cold water at a 1:3 ratio; stir over medium heat until the batter turns translucent and thickens to a loose paste, about 8–10 minutes. Remove from heat immediately.
Watch outStir the starch over medium heat until it turns translucent and thickens to a loose paste — pull it the moment it clears, it stiffens fast.
- 230 min
Pour the hot paste into a lightly oiled flat tray, smooth to about 2 cm thickness, and rest at room temperature for 30 minutes until fully set.
- 35 min
Bring a large pot of water to a rolling boil. Hold a ladle with small holes or a perforated spoon over the water and press portions of the slightly cooled paste through the holes, letting drops fall directly into the boiling water.

Cook the noodle drops for 2–3 minutes until they float to the surface and turn translucent. Lift out immediately with a slotted spoon and transfer to a bowl of ice water; chill for 2 minutes.
Watch outLift the pieces out the instant they float and turn clear, then straight into ice water — chilling sets that springy, non-sticky bite.
- 53 min
Prepare the dressing: whisk together black vinegar, chili oil, light soy sauce, minced garlic, and sesame oil in a bowl.
- 62 min
Drain the chilled noodles and divide into serving bowls. Ladle dressing generously over each portion.
