Kor Moo Yang (คอหมูย่าง)

The Cut Every Grill Wants

คอหมูย่าง is the Isan street-stall staple that made the pork neck the star of every Thai grill — skewered, laid over charcoal, sliced and piled next to sticky rice and som tum. Wongnai's recipe writer gives it a better name: คอหมูสะดุ้งไฟ, "the neck that flinches at the fire" — the cut is so marbled that the fat spits when the heat finds it.

The marinade is short work, and deliberately so: a home marinade runs thirty minutes; the shop versions go overnight. The flavourings are a fixed trio across the sources — salt, pepper, garlic, coriander root — sweetened and sauced. Where the sources part ways is the tenderiser: Wongnai's home recipe uses honey and evaporated milk, the dairy trick that keeps the outside from toughening before the inside cooks.

Then there's the dip. Nam jim jaew is the reason the dish travels: fish sauce, palm sugar, tamarind or lime, chilli flakes and — the non-negotiable — toasted rice powder, ground from jasmine rice dry-roasted in the pan. The smokiness of the jaew meets the smokiness of the charcoal and the neck does the rest.

One warning appears in Thai Hokkaido's version and belongs in every kitchen: cut the neck not too thick. Too thick, and the outside chars before the inside is done — the classic home-grill failure.

The Recipe (home version, from Wongnai)

The charcoal batch (TrueID): 1 kg pork neck, ½ tbsp peppercorns, 1 head Thai garlic, 1 tbsp palm sugar, 2 tbsp oyster sauce, 1 tbsp seasoning sauce, 1½ tbsp fish sauce — marinated overnight. The quick pan version (Golden Mountain): pounded salt, peppercorns, coriander root and garlic with 2 tbsp oyster sauce and seasoning sauce, rested just 15 minutes.

The Method

1. The poke. Fork the pork neck all over so the marinade has somewhere to go.
2. The marinade. Peppercorns, garlic and coriander root pounded, then mixed with salt, honey, light soy sauce, oyster sauce and evaporated milk. Pork in, 30 minutes minimum.
3. The jaew. Fish sauce, palm sugar, lime juice, tamarind water, chilli flakes and toasted rice powder stirred together — taste and adjust — then the herbs scattered on top.
4. The grill. Over medium-low heat, charcoal or a pan, until cooked through. Low and patient beats hot and blackened.
5. The slice. Thin slices on the diagonal, plated with lettuce, cucumber and tomato, jaew on the side.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Using loin instead of neck. Pork neck is marbled; loin is lean. The whole point is the fat melting through the meat as it grills.
• Searing over high heat. The sugar in the marinade blackens long before the inside cooks. Medium-low, patient heat, per every Thai source.
• Serving it with sweet chilli sauce. Kor moo yang is built for nam jim jaew — smoky, sour, chilli-hot. Bottled sweet chilli is a different dish.
• Cutting the neck too thick. Thai Hokkaido's warning: too thick and the outside hardens before the middle is done.
• Leaving out the toasted rice. The jaew's smokiness comes from ข้าวคั่ว, ground toasted jasmine rice. Skip it and the dip is just spicy fish sauce.

UK Ingredient Notes

• Pork neck: sold as pork neck fillet or pork collar at proper butchers; Chinese grocers stock the same cut. Ask for it — most supermarket counters can order it.
• Oyster sauce, light soy, fish sauce, palm sugar: any Thai grocer or the world-food aisle of a large supermarket.
• Toasted rice powder: make it — dry-roast jasmine rice in a pan until golden, then pound or blitz. Thai grocers sell it ready-made as ข้าวคั่ว if you'd rather.
• Evaporated milk: standard supermarket stock, the unsweetened kind (นมข้นจืด — the sweetened condensed kind would ruin the marinade).
• Charcoal: a garden BBQ with the coals settled to a low, even bed replicates the street stall; a heavy pan on medium-low does the job on a weeknight, per Wongnai.
