Steamed Sea Bass with Ginger and Spring Onion

What to expect

Taste

Almost nothing at first, and that is the point. Sea bass steamed plain is sweet, delicate, faintly mineral and very clean — there is no browning, no fat and no seasoning inside it, so what you taste is the fish. Everything else arrives around it rather than in it. The soy mixture is salty and slightly sweet, with the sugar softening the soy's edge. Raw ginger, shocked with hot oil, is hot and bright and citrusy in a way cooked ginger never is. Spring onion is sharp and green. Sesame oil is nutty and is the last note. Coriander is a top note. It is the least seasoned dish in this collection and one of the most precisely flavoured.

Aroma

Very little during the cooking — steaming produces almost no smell, which is itself informative, because a strongly fishy smell from the steamer means the fish was not fresh. Then a single dramatic moment: smoking oil hitting raw ginger and spring onion, which releases everything at once and fills a kitchen in about two seconds with a smell that is sharp, green and hot. Sesame oil goes on last and is the most persistent smell on the plate.

Texture

Silky. Steamed fish has a texture nothing else produces — moist, yielding, flaking into large soft pieces, with none of the firmness that dry heat gives. Against it, the ginger and spring onion stay crisp, because a second of hot oil wilts them without cooking them. That contrast between soft flesh and crisp raw aromatics is the dish's structure.

Sound

One sound and it is the reason the technique exists. Smoking oil poured slowly over raw aromatics produces a loud, sustained crackle for several seconds — if it does not crackle, the oil was not hot enough and the ginger will taste raw rather than bloomed. Everything else about the dish is silent.

How the flavour moves

Ginger and spring onion in the nose first, carried up by the hot oil. Then the fish itself, mild and sweet, then the soy arriving from the pool at the edge as you drag a piece through it. Sesame is the finish. The whole arc is quiet and short — there is no long finish here and none is wanted, because the next mouthful should taste as clean as the first.

Serve it

Hot, immediately. Steamed fish cools fast because it is thin and wet, and it is noticeably worse after five minutes. The plate should be warm and the fish should reach the table within a minute of the oil going over.

Goes with

Plain steamed rice, which is not optional — the soy is concentrated and the rice is what carries it. A simple green vegetable, blanched or stir-fried with garlic. A cold light beer, or a dry riesling, or Chinese tea. Where it fails is next to anything strong: this is a dish that must be the most delicate thing on the table, and putting it beside something rich wastes it.

Cook's notes

Difficulty

Technically easy and completely unforgiving. There is nothing difficult to do; there is also nowhere to hide. A fish that is not very fresh, or is steamed two minutes too long, is exposed entirely — there is no sauce, no crust and no browning to cover for it.

Cost

Moderate, and it is all the fish. Everything else costs pennies.

Equipment

A steamer large enough to hold a plate with a whole fish on it, which is the real constraint — a bamboo steamer over a wok, a stacking metal steamer, or a large pan with a trivet and a tight lid. A heatproof plate with a rim to hold the sauce. A small pan for the oil.

When to make it

Any time. It is light enough for summer and quick enough for a weeknight, provided the fish is right.

Best season

Wild sea bass has closed seasons and minimum sizes in UK and EU waters and stocks have been under real pressure; farmed sea bass and bream are available year-round and are the sensible choice.

You know it is done when

Push at the thickest slash: the flesh should come cleanly away from the backbone and be opaque white throughout with no translucent grey. The eye turns opaque white, which is the traditional cue and is reliable.

And it feels like

It should flake into large, distinct pieces rather than fall apart. Overcooked fish goes dry and slightly cottony and the flakes separate into strands.

Food safety

This dish depends entirely on the fish being very fresh, and there is no way to compensate. A fresh whole fish has clear, domed eyes, bright red gills, firm flesh that springs back, and smells of clean sea and nothing else. Cloudy sunken eyes, brown gills, or any ammonia smell means do not buy it. Cook it the day you buy it. The fish is cooked when opaque throughout at the bone.

Where it goes wrong

Leaving the steaming liquid on the plate, which makes the whole dish taste muddy. Not slashing the fish, so the thick part is underdone while the thin part is dry. Oil that is not properly smoking, so the aromatics never bloom and taste raw. Pouring the soy over the fish rather than around it. Steaming over water that is not at a hard boil. And overcooking, which is a ninety-second error.

If it does go wrong

Muddy or fishy: the liquid was not poured off, or the fish was not fresh — the second is not fixable. Dry: overcooked. Flesh still translucent at the bone: back in the steamer for two minutes, and check again. Ginger tastes raw and harsh: the oil was not hot enough. Skin torn: the fish was moved too much; lift it on the plate rather than transferring it.

Making it ahead

Nothing, and there is nothing to prepare beyond cutting the aromatics, which can be done an hour ahead and kept in cold water — which also makes shredded spring onion curl, which is the traditional presentation.

Keeping it

It does not keep. Steamed fish is a same-hour dish.

Reheating

No.

Freezing

No.

Leftovers

Cold picked flesh is good in fried rice the next day, and that is the limit of it.

Scaling it

Two fish need two steamers or two rounds, since they cannot be stacked without the top one dripping into the bottom one. This is a dish for two, or for a table where it is one of several things.

Substitutions

Any whole round fish of similar size — sea bream, grey mullet, trout, red snapper. Flat fish do not work as well because the flesh is thin and overcooks. Fillets can be steamed for four to five minutes and it is a lesser dish: the bone is doing real work, keeping the flesh moist and adding gelatine. Light soy sauce is essential and dark soy is not a substitute — it is thicker, less salty and would colour the fish brown.

Dietary swaps

Not adaptable. Contains fish, soya and cereals containing gluten from the soy sauce; tamari makes it gluten-free. Dairy-free and nut-free.

Shopping for it

This is the entire recipe. Buy from a fishmonger who will let you look at the fish: clear domed eyes, bright red gills, firm springy flesh, a clean sea smell. If the eyes are cloudy and sunken, choose something else or cook something else. Light soy sauce, not dark.

Keeping the cost down

A whole fish is cheaper per kilogram of edible flesh than fillets, once you account for the fact that you are not paying someone to fillet it. Ask the fishmonger to scale and gut it, which is free. Grey mullet and farmed sea bream are considerably cheaper than sea bass and work identically.

Sustainability

Worth taking seriously here. Wild sea bass has been overfished in the north-east Atlantic and is subject to catch restrictions; farmed Mediterranean sea bass and bream are abundant, cheap and a much better choice for this dish. Ask, and if the fishmonger cannot tell you where it came from, buy the farmed one.

Nutrition

Around 340 calories a serving. Sea bass is lean, high in protein and a good source of selenium and B vitamins; almost all the fat in the finished dish is the three tablespoons of oil poured over, and a fair amount of that stays on the plate. It is one of the lightest main courses in the collection.

Worth it?

Worth it, and it is the dish that teaches restraint better than anything else here. Nothing in it is difficult and everything in it is exposed, which means a good fish comes out extraordinary and a mediocre one comes out obviously mediocre. Learn the hot-oil finish — it takes ten seconds and you will use it on noodles, aubergine and tofu for the rest of your life.

Where it comes from

Origin

Guangdong province, southern China.

Also called

Qing zheng yu — 清蒸鱼 — literally clear-steamed fish. Qing means clear or pure and is doing a lot of work in that name.

Said out loud

ching jeng yoo, roughly.

What the name means

Clear-steamed. The word describes both the method and the intent: nothing added, nothing obscured.

History

There is no dated origin and it would be false to supply one. What is worth understanding is why Cantonese cooking is like this. Guangdong is subtropical, coastal, and historically had year-round access to live fish, live poultry and fresh vegetables — an abundance most of China did not have. Cuisines that developed around preservation, scarcity or long winters use strong seasoning because they must; a cuisine with a live fish tank at the front of the restaurant does not. The Cantonese emphasis on freshness and restraint is a direct consequence of geography, and this dish is its clearest expression. The technique of finishing with smoking oil is used across Chinese cooking and is worth learning on its own.

Why it matters

A whole fish is served at Chinese New Year and at banquets because the word for fish, yu, sounds like the word for surplus or abundance — the saying nian nian you yu means may there be surplus every year. Serving it whole, head and tail intact, is part of that symbolism, and there are conventions in some regions about not turning the fish over on the plate.

When it is eaten

New Year, banquets, family meals. It is both everyday and ceremonial depending on the fish.

The traditional way

Two, and both are in this recipe. Elevating the fish on aromatics so steam circulates underneath. And po you — pouring smoking oil over raw aromatics at the end, which blooms them instantly. The second is a general Chinese technique and appears in dishes from cold noodles to steamed aubergine.

How it changed

Very little. Home steamers have replaced wok-and-bamboo setups in many kitchens without changing anything material.

Regional variations

The Cantonese version described here is the plainest. Hunan steams fish under a heavy layer of chopped salted chillies and it is a completely different dish. Some versions add a little Shaoxing wine to the fish before steaming; some add fermented black beans.

How this version differs

It does not. It is the standard Cantonese method, stated with the three steps most Western versions leave out.
