Why the Pork Is Cooked Twice

Twice-cooked pork is the dish that tells you whether a Sichuan kitchen knows what it is doing, and it is not really a stir-fry. The first cooking is a bare simmer in water with ginger and scallion, which sets the shape of the meat and renders some of its fat. The second is a fast fry in its own fat with fermented bean paste. Everything distinctive comes from the gap between the two: how long the meat simmers, how cold it gets before slicing, how dry the slices are when they meet the wok.

Start with the cut. You want skin-on pork belly, a slab about 4cm thick with clear layers and skin 3 to 4mm deep. The skin is not decoration. Its collagen softens to gelatin during the simmer, and during the fry it contracts faster than the fat beneath it, which is what makes the slice curl. A skinless piece will taste fine, but the slices lie flat like bacon and the texture is even and dull.

Simmer for 25 to 30 minutes, no more. A chopstick should pass through skin and fat with a little resistance, and the very centre should still be faintly pink when you cut into it. Why this matters: pork cooked through at this stage is cooked twice by the time it reaches the table, and the lean layer turns to sawdust. The residual heat carries it the rest of the way as it cools.

Then chill it for 30 minutes. This decides whether you get slices or shreds. Cold fat is firm and holds a cut edge; warm fat smears under the knife and the lean layer tears away in ragged strips. Two millimetres is the target, about the thickness of a coin. The slices must also be dry: water has to boil off before the meat can brown, and while it boils the meat steams, the fat renders into a puddle and everything turns grey. Pat each slice and leave them spread out for ten minutes. Why this matters: browning cannot start until the surface water is gone. While that water boils off it pins the pan at 100°C, and at that temperature the Maillard reaction does not run — so a wet slice steams in its own fat and turns grey instead of curling.

In the wok the slices render at medium heat for 2 to 3 minutes, until the edges curl up and back like the rim of an old oil lamp. Sichuan cooks call this the lamp shape, and it signals that the fat has turned translucent and the skin has tightened. Only then do the aromatics go in, at about 160°C, for 20 seconds: hot enough to fry the paste, cool enough that it does not blacken. No oil is added at any point. The pork provides it, and a non-stick pan cannot do this properly, because the meat needs bare hot metal to catch and colour and the paste needs a surface it can grip for those twenty seconds.

Ingredients

For the first cooking

• 500g skin-on pork belly, in one slab about 4cm thick
• 1.5 litres water
• 4 slices fresh ginger (20g)
• 2 spring onions (30g), cut into 5cm lengths
• 1 tbsp (15ml) Shaoxing wine
• 1 tsp (5g) fine salt

For the fry

• 1.5 tbsp (30g) Pixian doubanjiang, chopped fine
• 1 tsp (5g) fermented black beans (douchi), rinsed and chopped
• 1 tsp (8g) sweet bean paste (tianmianjiang)
• 4 green garlic stalks (120g), or 200g leeks
• 1 tsp (4g) caster sugar
• 1 tsp (5ml) light soy sauce
• 1 tbsp (15ml) Shaoxing wine, for the wok

To serve

• 600g cooked jasmine rice, for 3 bowls
• 1 tsp (3g) chilli oil, optional

Substitution notes: Green garlic, the flat-leafed stalks sold in spring, is the classic partner; out of season use leeks cut on the diagonal, or the white parts of 6 spring onions, and give them 30 seconds longer in the wok. Sweet bean paste can be replaced with 1 tsp of hoisin sauce, in which case leave out the sugar, or with 1/2 tsp of sugar alone if you want the glaze without the extra fermentation. If you can only find skinless belly, add 1/2 tsp of dark soy for colour, and expect flat slices rather than curled ones.

Prep: Twenty Minutes, Plus a Thirty-Minute Chill

1. Trim and start the water (5 minutes)

Cut the string off if the belly has been tied and unroll it. Rinse the skin and scrape it with the back of a knife to lift any loose hair, then cut the slab into two pieces that fit your pan. Put 1.5 litres of water in a wide pot with the ginger, spring onions, Shaoxing and salt and bring it to a bare simmer, about 95°C.

2. Simmer for 25 to 30 minutes

Lower the pork in skin side down. The water should tremble, not roll; a hard boil shreds the surface of the skin and dries the edges. After 25 minutes, push a chopstick through the skin at the thickest part. It should go through with a little resistance, like a firm pear, and a sliver cut from the end should still be faintly pink at the centre. Lift the pieces out, drain in a colander for 5 minutes, then wrap and refrigerate.

3. Chill for 30 minutes, then slice 2mm

Thirty minutes firms the fat without drying the meat. Put the cold slab skin side up and cut across the layers, not along them, into 2mm slices. A long sharp knife and one confident stroke per slice work better than sawing; if the lean layer tears, the meat is still too warm and needs another 10 minutes. You should get 20 to 24 slices. Lay them on kitchen paper, cover with a second sheet, press gently, then leave them spread out while you finish the rest.

4. Cut the greens and mix the paste (5 minutes)

Cut the green garlic on a long diagonal into 4cm pieces, keeping whites and green tops in separate piles; the whites go in first and need 40 seconds more. Chop the doubanjiang until no lump is larger than a grain of rice, rinse and chop the douchi, and put the sweet bean paste in the same small bowl. Have the sugar, soy and Shaoxing within reach, because the last part of this dish takes 90 seconds.

Step by Step: Ten Minutes in the Wok

Step 1: Render the pork at medium heat (3 minutes)

Set a well-seasoned carbon steel wok over medium heat for 90 seconds. Do not add oil. Lay the slices in a single overlapping layer, skin side down where you can, and leave them for 60 seconds without moving them. They will hiss, then quieten as the surface water goes. Turn and cook another 60 to 90 seconds. The fat turns from opaque white to translucent, the edges lift and curl into the lamp shape, and a thin pool of clear fat collects in the base. If the slices sit in liquid rather than fat, the heat is too low; if they are browning hard and smoking, it is too high. Lift them out with a slotted spoon and leave about 2 tbsp of fat behind, pouring the rest into a jar.

Step 2: Fry the bean paste at 160°C (20 seconds)

Let the wok come back to about 160°C; the fat should shimmer but not smoke. Add the doubanjiang, douchi and sweet bean paste and stir with the ladle flat against the metal, pressing and circling, for exactly 20 seconds. The paste loosens into the fat, the oil turns dark scarlet and the smell goes from sharp and beany to toasted. Twenty seconds is the window: at 30 the paste starts to catch, and burnt doubanjiang is bitter in a way that ruins the dish. Return the pork at once and toss for 20 seconds, until every slice is coated.

Step 3: Add the green garlic, whites first (40 seconds)

Add the white parts and stir-fry for 40 seconds, until they lose their raw edge and turn glossy but still snap when bitten. Add the green tops, the 1 tsp of sugar, the 1 tsp of light soy and the 1 tbsp of Shaoxing, and toss for another 30 seconds. The wine steams off almost at once and leaves a faint sweetness; the sugar rounds the salt of the bean paste rather than making the dish sweet. Turn off the heat while the greens are still bright.

Step 4: Rest and serve (2 minutes)

Slide everything into a warm dish and let it sit for 2 minutes. The slices reabsorb some oil and the sauce tightens around them. A slice should be salty first, then fermented and savoury, with sweetness at the end and the greens still crisp. If it tastes flat, a few drops of light soy will fix it.

Key Pitfalls

The slices shred instead of cutting cleanly. The meat was still warm. Warm fat smears and the lean layer tears away in strips. Chill for a full 30 minutes, use a long sharp knife, and cut with one stroke per slice.

The pork steams and turns grey instead of browning. There was water on the surface, or the wok was not hot enough to drive it off. Pat every slice dry, leave them spread out for 10 minutes, and heat the wok until a drop of water vanishes in a second.

The dish is swimming in oil. The heat was too low during rendering, so the fat melted before the surface could seal, or the belly was too fatty. Render at medium, not low, and pour off all but 2 tbsp of fat before the paste goes in.

The bean paste tastes bitter and the oil is almost black. The wok was above 180°C, or the paste stayed in for 30 seconds or more. It needs about 160°C and 20 seconds. If it has caught, start again: the bitterness spreads through the whole dish and no amount of sugar hides it.

The pork is dry and chewy. It was simmered past 30 minutes, or the cut was too lean. Simmer until a chopstick passes with slight resistance, pull it while the centre is faintly pink, and buy a slab with a lean layer no thicker than the fat.

The green garlic is limp and khaki. The greens went in with the whites and stayed for a minute and a half. Whites first for 40 seconds, greens for 30. Turn the heat off while they are still bright; they carry over.

Nothing curls and the slices lie flat. The skin was removed, or the slices were cut too thick. The skin contracts faster than the fat and is what makes the lamp shape. Keep it on, slice 2mm, and do not score it.

It sticks and burns in a non-stick pan. Non-stick coatings cannot take a bare preheat, and the meat needs direct contact with hot metal to colour. Use carbon steel or cast iron, season it well, and keep the heat at medium.

Serving Suggestions

Serve it over plain rice in warm bowls, with the oil from the wok spooned over the top. The dish is rich enough that the rest of the table should be light: blanched greens with a little salt, or a cold cucumber salad with vinegar and garlic. Do not add another meat. Three or four slices per person is generous when the rice is hot and the sauce is right.

Cold beer or a plain roasted tea works better than wine; fermented bean paste and chilli flatten most reds. Leftovers keep three days and reheat well in a hot wok with a splash of water for 40 seconds, which brings the fat back to a glaze. Do not microwave it, or the slices tighten and leak oil.
