A thick Cantonese soup of shredded farmed snake, wood ear and mushroom in a three-hour old-hen broth, finished with lemon-leaf shreds and crisp wonton skin. Adapted for a home kitchen from the original ClouChef R&D report — 太史蛇羹, report 25.

Taishi soup is famous, and its fame rests on a stock that cannot be hurried: an old hen and snake bones simmered three hours without topping up the water, until the broth turns thick and milky-white and tastes of long cooking rather than of any single ingredient. The snake meat itself is treated with equal care — boned so the shreds stay whole, blanched thirty seconds, then simmered two minutes in the finished broth, never longer, so it stays silky inside a soup that is itself almost a sauce. Thickening with potato starch, poured slowly around the pan's edge while stirring in one direction, is what gives the soup its clinging, spoon-coating body; dumped in at once, the starch lumps and the soup turns gluey in patches. Lemon-leaf shreds, themselves blanched five seconds for safety, and a shard of crisp fried wonton skin on top give the final contrast of fragrance and crunch against the richness.
| Ingredient | US | Metric | Substitute / note |
|---|---|---|---|
| Farmed water snake (shuilü), live weight, yielding about 88 g meat | 8.8 oz live | 250 g | Specialist ingredient — farmed, non-protected water snake from a licensed supplier only, where legal. Do not use wild-caught or protected species, and never slaughter a live snake at home unless you are trained and it is legal to do so; buy pre-cut farmed snake meat instead (home safety adaptation). |
| Old hen, for stock | 3.5 oz | 100 g | For the stock only; the meat is not served. A stewing hen or mature chicken works (adaptation). |
| Water, for stock | About 2 cups, reducing to 300 ml | 500 ml | Simmered down to 300 ml per serving. |
| Dried wood ear, soaked | 0.35 oz | 10 g | Soaked and shredded. |
| Dried winter mushrooms (donggu), soaked | 0.5 oz | 15 g | Soaked and shredded. |
| Astragalus (beiqi) | 1 tsp | 5 g | For the stock; omit if unavailable (adaptation). |
| Codonopsis (dangshen) | ½ tsp | 3 g | For the stock; omit if unavailable (adaptation). |
| White pepper | Pinch | 0.5 g | — |
| Potato starch | 2 tsp | 8 g | Mixed with 20 ml cold water before use. |
| Lemon leaf shreds, blanched 5 seconds | ½ tsp | 2 g | Blanched in boiling water for 5 seconds before garnishing, per the report. |
| Crisp fried wonton skin | 1 tsp | 5 g | Fried until crisp; store-bought crisp wonton strips work (adaptation). |
Starch thickening fails in two ways: lumps from pouring into the centre, and a broken, watery soup from stirring back and forth. Pouring the slurry around the pan's edge lets it meet hot liquid gradually, and stirring in one direction keeps the starch network even, so the soup thickens to a smooth, clinging body instead of patchy glue. If it does lump, a few seconds of vigorous one-direction stirring usually rescues it.
Only from farmed, non-protected species bought through a licensed supplier, where local law allows it. Never use wild-caught or protected snakes, and cook exactly as directed — the blanching and the two-minute boil are safety steps.
The old hen and bones need that long to release gelatin and flavour without added water diluting the broth; topping up mid-simmer thins it.
Yes — the strained stock keeps 3 days refrigerated or freezes for 1 month; the final soup should be assembled just before serving.
Best eaten fresh. The strained stock keeps 3 days refrigerated or 1 month frozen. The finished soup keeps 1 day refrigerated; reheat to a full boil. Do not freeze the finished thickened soup — the starch breaks on thawing.

The report's pricing, margin and marketing sections are deliberately omitted here; no B2B cost is presented as a home-cook cost. The report's own cost summary contradicts its ingredient total, so no cost figures are reproduced. The pre-cut snake meat and no-snake-bone stock adaptations, and the legality warning, are home safety additions and are labelled as such. Original poster image: clouchef.com (太史蛇羹_25.jpeg).
