Gaeng Hang Lay — Northern Braised Pork Curry / แกงฮังเล

Ingredients

• For the paste
• 8 dried long red chillies, soaked in warm water 20 minutes, drained
• 2 stalks lemongrass, tough outer leaves removed, finely sliced
• 30 g galangal, peeled, roughly chopped
• 80 g shallots, peeled, roughly chopped
• 6 cloves garlic, peeled
• 40 g fresh ginger, peeled, roughly chopped
• 1 tsp ground turmeric
• 1 tbsp curry powder
• For the braise
• 800 g pork belly or shoulder, skin on if belly; cut into 4 cm pieces
• 60 ml tamarind water, made from tamarind paste dissolved in warm water, strained
• 500 ml water
• 2 tbsp palm sugar, shaved or grated
• 2 tbsp fish sauce
• 80 g pickled garlic (kratiam dong), whole cloves or halved; added near end of braising

Method

1. 1
   Pound the paste ingredients — drained dried chillies, lemongrass, galangal, shallots, garlic, ginger, turmeric, and curry powder — in a granite mortar, working from the fibrous to the fine, so that each coarse element is fully broken before the next is added and nothing escapes as whole fibre into the finished paste. The paste is ready when it is homogeneous, no visible fibre remains, and the colour has shifted to a deep ochre-red from the turmeric and chillies.
2. 2
   Heat a heavy braising vessel over medium-high heat, add a film of oil, and fry the paste, stirring constantly, so that the raw, sharp smell of the alliums cooks out and the paste develops a deeper, rounder fragrance before the pork goes in. It is done when the paste deepens in colour and the oil begins to separate at the edges of the mass.
3. 3
   Add the pork pieces and turn them through the paste until each surface is fully coated and the meat has lost its raw colour on all sides, so the paste bonds to the fat and flesh now rather than washing off once the liquid is added. Any grey-white surface signals the pork is sealed.
4. 4
   Pour in the tamarind water and the water, bring to a simmer, then reduce the heat to low and add the palm sugar and fish sauce, stirring to dissolve the sugar. This is where the dish lives or dies: the braise must continue at a gentle, unhurried simmer for a minimum of 60 to 90 minutes, because only at that pace will the fat render fully into the liquid and the sauce reduce to the dark, unctuous, clinging, mahogany-brown glaze that defines gaeng hang lay — a rushed, rolling boil gives you pale, greasy broth instead.
5. 5
   Add the pickled garlic (kratiam dong) in the final 15 minutes of braising, so they warm through and absorb the braising liquid without sitting long enough to turn soft and formless. They should be yielding but still hold their shape when pressed.
6. 6
   Taste and adjust the balance of tamarind water (acidity), palm sugar (sweetness), and fish sauce (salt) until the characteristic sweet-sour note is present and in equilibrium with the richness of the pork fat. Rest overnight if time permits, so the sauce penetrates the meat fully and the flavour deepens materially on reheating the following day.
