A soothing Putian soup of coastal razor clams coated in potato starch and slipped into a ginger-garlic broth, creating a silky, clear bowl that coastal villages of the historical Xinghua region have served for generations.
The razor clam (缢蛏) has been farmed in Putian's coastal mudflats for at least six centuries; Ming-dynasty gazetteers explicitly document clam-field cultivation across Fujian's coast, and the finest specimens are traditionally harvested from Hanjiang district's Duotou mudflats. A folk legend explains the dish's name: during a past coastal epidemic across central Fujian, villages near the sea that routinely ate razor clam broths suffered far fewer deaths. Folk healers spread the observation, and communities began cooking razor clam soup; when the epidemic passed, people said the plague had slipped away. The character 熘 (to flash-cook) later became a secondary spelling emphasizing technique, but the original 溜 (to slip away) survives as the colloquial name.
Each clam slides across the tongue in a starchy, silky coat; the broth is clean and oceanic, shot through with the warmth of ginger. A thread of rice vinegar lifts the finish, and the aftertaste lingers long after the clam has gone.
Coating razor clam meat in dry starch serves two roles: upon contact with boiling water, the starch gelatinizes instantly, sealing the clam's amino acids and juices within a thin gel layer; this same gelatinized film gives the signature silky mouthfeel on the tongue. Clam muscle proteins begin denaturing at 65–70°C and rapidly toughen above 80°C, so the three-minute cooking window is critical. Rice vinegar's acetic acid binds with volatile trimethylamine compounds in the clam—the primary source of fishiness—forming salts that reduce off-odors and keep the broth clear.
Variations
Sea oyster version (海蛎溜) replaces razor clams with fresh oysters; some Putian households stream beaten eggs into the broth at the end for a richer texture. Increasing the starch ratio thickens the dish toward a true congee-soup, which is the same preparation under a slightly different name.

How it's made
7 steps · 15 min
- 110 min
Scrub razor clam shells under cold running water. Prise open, extract the meat, and pull away the dark mantle fringe. Rinse the meat in lightly salted water and drain.
- 23 min
Blot razor clam meat dry with a clean cloth. Place in a bowl and toss with 2 tablespoons of dry potato starch until each piece is evenly coated.
Watch outBlot the clam meat bone-dry before dusting, so the starch clings in a thin even film — wet meat clumps the powder and the coating slides off in the pot.
- 33 min
Smash garlic cloves; slice ginger into thin coins. Trim scallions and cut into 3 cm lengths.
- 42 min
Heat oil in a wok over medium heat; add garlic and ginger, stir-fry 30 seconds until aromatic. Pour in 700 ml cold water and bring to a rolling boil.
Watch outWait for a full rolling boil before the clams go in — a lazy simmer lets the coating melt away instead of setting into that silky skin.
- 53 min
Gently lower the starch-coated clam meat into the boiling broth. Stir once, cover, and cook exactly 3 minutes.
Watch outTime it to exactly three minutes — clam muscle turns rubbery past 80°C, so pull it the moment it's just set.
- 61 min
Add salt, white pepper, and scallions. Stir in 1 teaspoon rice vinegar; taste and adjust seasoning.
- 71 min
Ladle immediately into bowls, drizzle a few drops of sesame oil on top, and serve at once.
