Cơm tấm: what broken rice is, what to order, what to avoid

Overview

Cơm tấm means “broken rice”, and the name is the whole story. Tấm is the fragments — grains snapped during milling — that were once sorted out and sold cheap, the rice a household bought when it could not afford the whole grain. It cooks softer and stickier than intact rice, clumping in a way that a plate and a fork can manage, and it carries sauce into itself rather than sitting under it. What began as the food of poor Mekong Delta farmers in lean seasons became, as people moved to the city through the twentieth century, the everyday plate of this one above all others. There is a local line that Saigon eats cơm tấm the way Hanoi eats phở — it names the dish as the city’s own, not the country’s.

The other thing that marks it out is small and telling: it is eaten with a fork and spoon, not chopsticks. That is partly the broken grain, which does not lift in a clump, and partly the plate itself, which the dish adopted as the city’s kitchens took on French and other outside habits. A bowl-and-chopsticks dish it is not, and never was in its modern form.

At its simplest it is a plate of that soft broken rice with one grilled pork chop and a little sauce. Built up, it is one of the most generous single plates in Vietnamese cooking.

What to order

The full name tells the kitchen what to pile on. Cơm tấm sườn bì chả is the classic trio, and each word is a distinct thing:

• sườn — a grilled pork chop, usually flattened, marinated in fish sauce, garlic, lemongrass and a little sweetness, then cooked over charcoal until the edges char. This is the part everything else is judged against. If you want only this, ask for cơm sườn and you will get rice and the chop.
• bì — fine shreds of pork and pork skin tossed with thính, a toasted-rice powder that gives it a nutty, slightly sandy texture. Cool and chewy against the hot chop.
• chả — here specifically chả trứng, a steamed pork-and-egg loaf, dense and savoury, cut into a wedge. Not to be confused with the fried chả giò rolls; on this plate chả means the loaf.

Two more words are worth having. Ốp la is a fried egg, runny-yolked, added on top for a small extra charge — a very common addition at breakfast. Mỡ hành is a spoonful of warm scallion oil, chopped spring onion softened in hot oil, poured over the rice; it is what makes the plate smell the way it does and you want it.

The plate arrives with sliced cucumber and tomato and a little dish of đồ chua, pickled carrot and daikon. And it arrives with nước mắm — but not the clear dipping sauce of other dishes. Here it is nước mắm pha, fish sauce let down with water, sugar, lime and chilli into something thick and almost syrupy, and the local move is to pour it over the whole plate, rice included, not to dip. Ask for it if it does not come already on; a cơm tấm eaten dry is a cơm tấm eaten wrong.

What to avoid

The chop is where a good stall and a lazy one separate, and the sign is smoke. A real cơm tấm stall grills to order, or in fresh batches, over charcoal on the pavement, and you can smell it down the street before you see it. A place that keeps trays of pre-grilled chops warming all day and drops one cold onto your rice is serving you something reheated; the meat will be dry at the edges and greyish rather than caramelised, and the charcoal smell will be missing entirely. Follow the smoke and the morning queue of people in work clothes rather than a shopfront with nothing cooking in view.

Watch the rice itself. The point of the dish is the broken grain — soft, small, faintly clumping. Some places serving a tourist-facing version quietly plate ordinary whole rice, which is firmer and separate; it is cheaper for them and it is not the thing. If the rice looks like the rice you would get with any other dish, it is.

Beware the plate built for a photograph rather than a meal: the single enormous bone-in sườn cây balanced across the rice is real enough as an option, but when it is the whole selling point — one giant rib and little else, at a price well above the neighbourhood rate — you are buying the picture. Around the backpacker strip you will also find cơm tấm served in air-conditioned comfort at two or three times a street stall’s price; the comfort is genuine, the dish is rarely better, and the version worth crossing town for is the one on the low stools.

Practicalities

Cơm tấm is, at heart, a morning and midday plate — it began as a breakfast the working city ate before the heat, and the charcoal grills are busiest early. Many stalls sell out their good chops by the middle of the afternoon and simply stop; you can find it in the evening, but the surest eating is between breakfast and lunch, when the grill has just been lit and is running hardest. If a stall has a line at seven or eight in the morning, that is the information you want.

A full plate at a street stall runs roughly 30,000 to 60,000 đồng — a pound or two — with the fried egg and extras nudging the top of that. A number well below it usually means whole rice and a thin, reheated chop; a number well above it, outside a proper sit-down restaurant, is the postcode or the air-conditioning talking, not the cooking.

It is ordered at the stall, plated straight away and eaten on the spot at low tables. Carry cash — the pavement grills deal in it, and while the city’s cafés and shops take cards and phone payments freely, the one-dish stalls where this is best are the likeliest to take only notes. Eat it while the chop is still hot from the coals and the scallion oil is still loose across the rice; it is a plate that goes flat as it cools.
