Garlic, butter, a splash of wine and a wok full of clams. Fifteen minutes and lala is on the table, the way almost every Singapore coffee shop zi-char stall does it. The cooking is the easy part. Buying and soaking are where this dish is won or lost.
The usual problem. You bite down and get a mouthful of sand. Or half the wok stays shut and you are not sure what to do with those. Neither is a wine problem or a garlic problem. One is a soak you skipped, the other is a decision you make at the counter before you ever turn on the heat.
Buy clams that are still alive
Live clams sit shut, or shut themselves when you tap the shell.1 Tap a few. Skip the ones that stay gaping, and skip anything with a cracked or broken shell. That tap is the whole quality check, and it costs you ten seconds.
Buy them cold, not off a tray sitting at room temperature. Get them into your fridge the moment you are home, and cook them the same day. Only buy what you are cooking tonight. Raw clams do not keep, so stocking up is just throwing money in the bin two days early.
Soak the sand out first
Lala live buried in sand, and they hold it inside the shell. This is the single biggest complaint people have with the dish, and it is fully fixable. Soak the clams in a bowl of salted water for about 30 minutes before cooking. That is long enough for them to push the sand out. If the water goes cloudy fast, drain it and soak in a fresh batch for another 15 minutes.
Salted water, not tap water. Then rinse the shells under running water and scrub off any mud or grit stuck to the outside. Grit on the shell ends up in your sauce.
What you need
The wok
- 600g fresh lala clams
- 4 cloves garlic, minced
- 2 tbsp butter
- 1 tbsp cooking oil
- 100ml white wine (Shaoxing wine works too)
The finish
- 1 red chilli, sliced (optional)
- 2 stalks spring onion, cut into short lengths
- A small handful of coriander leaves
- 1 tsp light soy sauce
- A pinch of white pepper
How to cook it
Start the butter. Melt the butter with the cooking oil in a wok over medium heat. The oil stops the butter catching.
Garlic, briefly. Add the garlic and stir until fragrant. Do not let it brown. Brown garlic turns bitter and you cannot take it back out.
Clams in, heat up. Turn the heat up, add the clams, and toss for a minute.
Wine, then lid. Pour in the wine, cover the wok, and let the clams steam until the shells open, usually 3 to 5 minutes. The lid is doing the work here, so leave it on.
Check every clam. Lift the lid and look. Throw out any that did not open fully.2 Do not pry them open to save them. Bigger clams need longer, so give the wok another minute before you call it.
Season and serve. Add the soy sauce, chilli, spring onion and white pepper. Toss for another 30 seconds. Scatter coriander on top and serve straight from the wok, with the sauce for dipping.
Serving it Singapore-style
Most zi-char stalls send this out with toasted or steamed mantou to mop up the garlic wine sauce. That sauce is half the dish, so give people something to catch it with. Steamed white rice works just as well if you want a full meal.
Storing and handling
Live clams go in the fridge, kept damp, and SFA is specific about the rest: not on ice, not sitting in fresh water, not in an airtight container.3 They are still breathing, and a sealed tub of tap water kills them.
Working with frozen clam meat instead of live clams? Thaw it in the chiller, never on the kitchen counter, and cook it as soon as it is thawed.4 Cooked leftovers go in the fridge in a sealed container, and are best eaten within a day.
Start with clams worth the wine
Fifteen minutes of cooking cannot fix a bad clam. Buy them shut, soak them properly, and the dish makes itself.

- Singapore Food Agency, Safety of Bivalve Molluscs such as Cockles, Oysters, Clams, Mussels and Scallops: “Only eat shellfish that open during cooking. Throw out any shellfish that do not open fully after cooking.” The same guidance notes that because bivalves “eat by taking in and filtering water, they readily accumulate bacteria, viruses and toxins in their bodies”, and to cook them thoroughly, “increasing the cooking time if the shellfish is larger”. sfa.gov.sg ↩︎

- Singapore Food Agency, Guidelines on Thawing of Food (updated 27 Sep 2024): “Frozen food should therefore not be left to thaw at room temperature, to prevent food poisoning bacteria that may be present from multiplying to high levels. Frozen food is recommended to be thawed in the chiller maintained at a temperature not below 0ºC and not above 4ºC, or by using a microwave oven.” The same document says to “Cook thawed meat immediately and do not refreeze thawed food”, and puts the “Temperature Danger Zone” between 5°C and 60°C. sfa.gov.sg (PDF) ↩︎
