The Dim Sum Trail: A Morning of Yum Cha

There is a particular sound that means Saturday morning in Hong Kong. It is the sound of a dim sum hall in full flow: the hiss of steam escaping a lifted bamboo lid, the percussion of porcelain on marble, the rising and falling tide of Cantonese conversation, and underneath it all the trundle of a trolley making its rounds. To sit down inside that noise, with a pot of tea and an empty plate in front of you, is to take part in something the city has been doing, more or less unchanged, for well over a century.

The ritual is called yum cha, which translates, plainly and a little misleadingly, as "to drink tea." The tea is the constant. The dim sum, those small steamed and fried parcels that arrive in waves, are technically the accompaniment, though no one has ever gone for the tea alone. Yum cha is the whole occasion: the family gathered three generations deep, the newspaper folded beside the chopsticks, the slow unhurried grazing that can stretch from mid-morning into the afternoon.

A grammar of small courtesies

Before the food, the manners, because they are half the pleasure and they reveal how communal the whole affair is meant to be.

The first thing you will notice is the tapping. When someone fills your cup, you bend two fingers, the index and the middle, and tap them gently on the table beside it. This is a silent thank you, useful precisely because it lets you express gratitude without breaking off your conversation or interrupting the flow of the table. The gesture has a charming origin story, told and retold over countless pots of tea, in which an emperor travelled in disguise and poured for his servants, who could not kowtow without revealing his identity, and so bowed with their fingers instead. Whether or not it is true hardly matters now. The point is that the courtesy is built into the table.

The second thing concerns the teapot itself. When your pot runs dry, you do not wave or call out. You simply lift the lid and rest it ajar, balanced on the rim or tipped to one side. A passing member of staff reads this instantly and arrives to refill it with hot water. It is a small piece of wordless choreography that keeps a busy hall moving.

And the third rule is the one that says the most about the spirit of the thing: you pour for others before you pour for yourself. You fill your neighbour's cup, your elder's cup, the cup of the person across the table, and only then, last of all, your own. To pour for yourself first would be to miss the entire point of the meal, which is that you are there to look after one another. The youngest at the table often ends up as the unofficial keeper of the pot, and there are worse ways to learn generosity.

What to order, and in what order

A first-timer can be forgiven for feeling adrift in front of a long menu or a parade of trolleys, but the canon is reassuringly short. Master these half-dozen dishes and you have the architecture of a proper yum cha. Order them, and the rest is improvisation.

Har gow come first for most people, and rightly so. These are the crescent-shaped shrimp dumplings, the kitchen's quiet showpiece, wrapped in a translucent skin so thin you can see the pink curl of the prawn through it. A good one holds at least seven pleats along its seam, the test that separates a careful kitchen from a careless one. The skin should have a faint chew, the filling a clean snap.

Siu mai are their constant companion: open-topped pork dumplings, sometimes flecked with prawn and crowned with a dot of orange, usually crab roe. They are sturdier than har gow, savoury and satisfying, the workhorse of the basket.

Char siu bao introduce the bun. Inside the soft, faintly sweet, cloud-white dough waits a tangle of barbecued pork, glazed dark and sticky in its sauce. The contrast of the pillowy bun and the rich, sweet-salty filling is one of the great simple pleasures of the Cantonese table. (You will also find them baked, golden and glossy, but the steamed version is the classic.)

Cheung fun arrive as wide, silky sheets of rice noodle, rolled around prawn or char siu or sometimes a sliver of fried dough for texture, then drizzled at the table with a thin sweetened soy. They are slippery, soft, and quietly luxurious, the dish that most rewards a steady hand with the chopsticks.

Lo bak go, the turnip cake, is the savoury anchor. It is made from grated white radish set with rice flour, studded with dried shrimp and Chinese sausage, then sliced and pan-fried until the edges crisp and the centre stays soft. It tastes of patience and of home.

And to finish, the egg tart. The pastry shell, the wobbling custard set just to the point of trembling, the faint caramel of the top: it is the sweet full stop at the end of a savoury sentence, and ordering one is how a table signals, without anyone saying so, that the meal is winding down.

This is the spine. Around it you might add lotus-leaf parcels of glutinous rice, deep-fried taro dumplings, spareribs steamed with black bean, or a bowl of congee. But the six above will never let you down.

The spectrum, from trolley to three stars

Part of what makes yum cha a daily comfort rather than an occasional treat is that it exists at every price and every register, and the same small dishes anchor all of them.

At one end are the grand old trolley-service halls, the ones with rooms the size of aircraft hangars and tablecloths and a din you could lean against. Here there is no menu to puzzle over. You point. The trolleys come past stacked with steaming baskets, the staff calling out what they carry, and you lift a lid, take a look, and nod or wave them on. A card on your table gets stamped with each dish, and the bill is the sum of your appetite. It is dim sum as theatre, and as a slightly thrilling guessing game.

In the middle sits a Hong Kong success story that needs little introduction. Tim Ho Wan earned a Michelin star while charging less than a cinema ticket for its dishes, and its baked char siu bao, with a crackly sugar-crusted top, became famous around the world. The queues are real and the stools are humble, but it remains the city's great proof that excellence and value are not strangers.

At the far end is the white-tablecloth Cantonese of Lung King Heen, the restaurant at the Four Seasons that became the first Chinese restaurant anywhere to hold three Michelin stars. The har gow here are made with the same logic as the ones on the trolley, only refined to within an inch of perfection, and served with a view of the harbour. It is yum cha dressed for an occasion, but it is recognisably the same meal.

That is the quiet genius of the institution. A billionaire and a bus driver can both spend a Sunday morning eating har gow and siu mai, tapping two fingers in thanks, lifting the lid for more tea. The setting changes. The grammar does not. And whether you are pointing at a passing trolley or studying a three-star menu, the morning unfolds the same way: slowly, sociably, one warm basket at a time.
