Kua Kling — Southern Dry Curry Stir-Fry / คั่วกลิ้ง — Cook

Ingredients

For the Southern curry paste
8–10 dried red chillies, Southern variety; soaked briefly then drained
3 stalks lemongrass, lower third only, finely sliced
30 g galangal, peeled, finely sliced
1 tsp ground turmeric, or 15 g fresh turmeric, peeled and sliced
80 g shallots, peeled and roughly chopped
2 tsp kapi (shrimp paste), generous measure; roasted if using raw block
500 g minced pork, minimum 20% fat — shoulder grind preferred
30 ml neutral oil
6 kaffir lime leaves, very finely chiffonaded; added in the last 30 seconds

Method

1
Pound or blend the soaked dried chillies, lemongrass, galangal, turmeric, shallots, and kapi to a fine, homogeneous paste, working each fibrous ingredient down before adding the next so the pestle can grip them cleanly rather than skating over them. The paste is ready when no fibrous strands remain and the mass holds together as a single cohesive body — any remaining threads of lemongrass or galangal will stay raw in the finished dish, where no amount of heat will soften them later.
2
Set a wok over the highest available heat, add the oil, and when it shimmers, add the paste, spreading it across the surface so every part of it meets the hot metal rather than steaming in its own moisture. Fry the paste, stirring constantly, until the raw, sharp fragrance has given way to a deep, roasted aroma and the oil has visibly separated back out around the edges of the mass — that ring of returning oil tells you the water bound inside the paste has cooked off and the aromatics are now frying, not boiling. This full development of the paste before any protein is added is where the dish lives or dies — under-cooked paste at this stage cannot be corrected once the meat is in.
3
Add the minced pork in one addition and raise the heat immediately if it has dropped, so the meat seizes against the hot wok rather than releasing liquid and beginning to stew. Stir and press the meat continuously against the wok surface, breaking up any clumps, so that every particle of meat is coated in paste and in direct contact with the hot metal — no liquid, no water, no stock, is added at any point. Continue until the fat rendered from the pork has been fully absorbed back into the paste-meat mixture and no pooled liquid remains in the wok.
4
Continue the high-heat dry-fry, stirring constantly, until the mixture is separate, crumbled, and intensely fragrant, each piece individually coated in caramelised paste — if you stop too soon the residual moisture will make the finished dish taste flat and slightly raw at the centre. The correct texture is a dry crumble, not a moist stir-fry; touch a small amount between finger and thumb and it should feel dry and slightly sandy, not yielding or wet.
5
In the final 30 seconds, add the kaffir lime leaf chiffonade and fold it through so the heat of the dry mixture draws out the leaves' fragrance without cooking away their brightness. Remove from heat the moment the leaves have wilted and released their perfume into the dry mixture, as even a few extra seconds on the flame will dull the clean, citrus lift they are there to provide.
