Why this works
The report treats patience as an ingredient. River snails must purge in clean water with a little salt and sesame oil for a full 48 hours, with three or four water changes, or grit survives into the finished dish — no amount of chilli can hide it. Once purged and tail-clipped, the cooking is fast and loud: aromatics fried in oil at 180 °C or above so the perilla releases its fragrance, a two-minute blast with the snails, then beer and water braised for eight minutes, and a final two-minute reduction until the sauce is thick enough to coat the shells. That last reduction is judged by eye — about a third of the original liquid left — because a watery sauce slides off the shells and a dry pan burns. The perilla matters as much as the chilli: it cuts the river flavour and gives the dish its distinctive herbal top note.

Ingredients
| Ingredient | US | Metric | Substitute / note |
|---|---|---|---|
| Live river snails | 18 oz | 500 g | Buy from a fishmonger; farmed snails sold cleaned still need purging (adaptation). |
| Perilla leaves | 1.1 oz | 30 g | Asian grocery; no close substitute (adaptation). |
| Pickled chillies | 1.4 oz | 40 g | Pickled red chillies; fresh chillies plus a splash of vinegar are an approximation (adaptation). |
| Garlic, minced | 0.7 oz | 20 g | — |
| Ginger, minced | 0.5 oz | 15 g | — |
| Doubanjiang (chilli bean paste) | 1.1 oz | 30 g | Pixian doubanjiang preferred. |
| Sugar | 0.4 oz | 10 g | — |
| Salt | 0.2 oz | 5 g | — |
| Beer | 6.7 tbsp | 100 ml | Any lager. |
| Water | 13 tbsp | 200 ml | — |
| Cooking oil | 2.0 tbsp | 30 ml | — |
Equipment
- Wok or large skillet — no wok required (adaptation)
- Large bowl for purging
- Kitchen scissors or shears for clipping snail tails
Steps
- Purge the snails. Soak the snails in clean water with a little salt and sesame oil for 48 hours, changing the water 3–4 times. Drain, clip off about a third of each tail end, wash and drain.
- Bloom the base. Heat 30 ml oil to 180 °C, add garlic, ginger, pickled chillies and doubanjiang, and stir-fry over medium heat for 1 minute until red oil appears and it smells fragrant.
- Sear the snails. Add the snails and stir-fry over high heat for 2 minutes, then add the perilla leaves and toss until they soften and release their fragrance.
- Braise. Pour in the beer and 200 ml water, add salt and sugar, bring to a boil, then simmer over medium heat for 8 minutes.
- Reduce and serve. Turn to high heat and reduce for about 2 minutes until the sauce is thick and coats the shells, leaving a little sauce in the pan. Serve at once.

Technique: Technique: purge fully, reduce by eye
Under-purged snails are gritty, and the report is absolute about 48 hours. At the other end, the braise has a narrow window: under eight minutes the snails taste unseasoned, over eight the meat toughens. Judge the reduction by the sauce clinging to shells, not by the clock alone — about one third of the liquid should remain.
Variations
- Less spicy: halve the pickled chillies and doubanjiang; the perilla and beer still carry the dish.
- No beer: replace the beer with the same amount of water plus a teaspoon of cooking wine — the flavour is flatter, but the method is unchanged.
Frequently asked questions
Why clip the tails?
Clipping about a third off the tail lets the sauce enter the shell and makes the meat easier to suck out.
Can I shorten the purge?
The report says no: under 48 hours leaves grit. If your supplier sells pre-purged snails, follow their guidance and rinse well.
Are the snails fully cooked?
Yes — the 8-minute braise plus the high-heat reduction cooks them through; the meat should be firm, not rubbery.
Storage
Best eaten fresh. Leftovers keep 1 day refrigerated; reheat until boiling throughout and do not reheat more than once. Discard any snails that smell off.
