Season pork with fish sauce and set aside
Pound curry paste in a mortar and pestle: first the chillies, then shallots, garlic, turmeric, lemongrass, galangal, and finish with shrimp paste
Heat a pot on medium and render fat from the pork pieces, then remove pork
Add curry paste into the pork fat with garam masala and fry for 3-4 minutes until fragrant
Add pork back in and sear and coat well for about 5-6 minutes
Add water just to cover, then add dark soy sauce, tamarind, jaggery, and extra garlic cloves
Bring to a simmer, cover, and cook on low heat for 1.5 hours
Once oil splits, uncover and simmer until thick, glossy and reduced
Finish with fresh ginger and coriander leaves
Serve with jasmine rice
