Typhoon Shelter Fried Crab (避風塘炒蟹)

// SUPPLY LIST

// OPERATIONS

1. 1 Chill the live crab in the freezer for 45-60 minutes, until a prod to the eye stalk and a pull on a leg get no response at all: this is both the humane way to kill it and the only way to joint it without it shedding claws in panic. A 850 g crab is still sluggishly alive at the half-hour mark, so give it the full hour rather than trusting stillness alone. Do not substitute a crab that was already dead at the fishmonger, because crab meat begins breaking down to mush within a couple of hours of death and no amount of frying will firm it up again.
2. 2 Pull back the triangular apron on the underside and snap it off, lever the top shell away from the body, then scrape out and discard the feathery grey gills along both sides and the gritty stomach sac sitting just behind the eyes, scraping any orange roe and the soft mustard into a small bowl and reserving it. Rinse the body briefly under cold water, halve it down the centre line with a heavy cleaver, cut each half into 2-3 pieces so that every piece keeps a leg attached, and crack each claw in two places with the spine of the cleaver so the seasoning can get inside.
3. 3 Spread the crab pieces cut-side up on a tray lined with kitchen paper and leave them for 10 minutes while you deal with the garlic, then blot the cut faces again until they look matte. Surface water is what makes hot oil erupt when the crab goes in, and it is also what makes the starch coating slide straight off in the fryer.
4. 4 Mince the garlic by hand with a cleaver to roughly the texture of coarse couscous, then tip it into a sieve, rinse under cold running water for about 20 seconds until the water runs clear, and wring it in a clean tea towel until it feels like just-damp sand. Do not use a food processor: it bruises the garlic into a wet purée that clumps into lumps which scorch on the outside while staying raw inside, and washing off the sticky surface sugars is precisely what lets the grains fry separately and stay sweet.
5. 5 Put 400 ml of the peanut oil in a small heavy saucepan over low heat and bring it to 120°C/250°F, at which a test grain of garlic fizzes lazily rather than sizzling, then add all the garlic at once and stir constantly with wooden chopsticks for 8-12 minutes. For the first several minutes the surface will foam hard as the water drives off; when that foam subsides to a lazy simmer the garlic starts to colour, and the moment the grains turn pale straw-blond and still look slightly underdone, lift them out with a fine mesh skimmer onto a paper-lined tray and spread them thin. Carry-over heat takes them to full gold within the next 30 seconds, and anything darker than gold is irreversibly bitter and will ruin the whole dish.
6. 6 Strain the garlic oil through a fine sieve lined with muslin into a clean pan and return it to the heat, because the fine garlic silt left behind will scorch the instant you go above frying temperature and turn every later batch bitter. Raise the strained oil to 160°C/320°F, fry the crushed panko for 30-45 seconds until it is sandy gold, lifting it out the moment it colours because crushed crumb goes from gold to burnt in seconds; then drop in the chopped dried shrimp for about 40 seconds until they curl and smell toasty, and drain those separately. The shrimp must be squeezed and patted genuinely dry first or they will spit violently and steam themselves leathery instead of crisping.
7. 7 Measure 3 tablespoons of the garlic-scented oil into a small bowl and set it aside for the finishing stir-fry, then pour the rest into a 30-35 cm carbon steel wok and top it up with fresh peanut oil to around 800 ml, which should come no more than one-third of the way up the wok. Any deeper and the oil will climb the sides and go over when the crab goes in.
8. 8 Smear the reserved roe and mustard over the cut faces of the crab pieces, put the potato starch in a shallow bowl and press only those cut faces and the cracked claw joints into it, tapping off all but a thin film. Coating the whole shell achieves nothing except steaming the meat inside a jacket of gluey starch that then peels away in the wok.
9. 9 Heat the oil to 180°C/356°F and fry the crab in two batches so the temperature never drops below 165°C/330°F, turning and spooning oil over the pieces since they will not be fully submerged: claws and the two largest body pieces for 4 minutes, the remaining body pieces for 3 minutes, until the shell is a uniform scarlet and the starched faces are crisp and pale gold. Take them out on the early side, because one minute too long turns the meat cottony and stringy and no quantity of crumb on top will rescue it.
10. 10 Carefully pour off the frying oil, wipe the wok out, set it over medium heat with the 3 tablespoons of reserved garlic oil, and fry the dried chilli rings for 20 seconds until they darken by one shade and smell toasty, then add the black beans and the fried shrimp and stir for a further 30 seconds until the beans smell winey and savoury. If the chillies blacken at any point, tip the lot out, wipe the wok and start this step again, because burnt chilli will scent the entire dish with acridity.
11. 11 Return all the crab to the wok, turn the heat to high, splash the Shaoxing wine around the hot rim of the wok so that it flashes to steam rather than pooling in the base, and toss for 45-60 seconds until every piece is coated in the chilli and black bean oil and the wok smells of hot wine and shellfish.
12. 12 Stir the sugar, salt, white pepper and chicken powder together in a small bowl first so they scatter evenly instead of landing in salty pockets, turn the heat off completely, then fold in the fried garlic, the fried crumbs, the seasoning mix, the spring onion greens and the fresh chilli, tossing for 30-40 seconds in the wok's residual heat alone. Taste a pinch of the crumb before you add the last of the salt, because the black beans, dried shrimp and chicken powder are already salty and this is the point at which the dish tips over. This is the step home cooks get wrong: even 20 seconds of live flame under the garlic here turns the entire crumb bitter, and there is no way back from it.
13. 13 Pile the crab onto a warmed platter, scrape every last crumb out of the wok over the top, and let it stand for 2 minutes so the crumb settles into the crevices and the meat relaxes off the shell. Serve immediately with plain jasmine rice, an empty bowl for shells, finger bowls and crab crackers, and cold beer; the crumb that falls onto the rice is what people go back to the stalls for, so spoon the rest of it over as you eat.
