– Heat a small amount of oil in a wide based pot or deep pan on medium heat. Add lemongrass, chillies, shallots, galangal and garlic. Fry until fragrant (approximately 1-2 minutes). Add sugar, coriander, cumin, cinnamon, pepper and tomato paste, mix well and fry for another 1 minute. Add fish sauce and coconut cream and bring to a simmer.
– Add fish to the pot. Coconut liquid should just cover the fish, if necessary add a little water. Simmer until fish is just cooked through (approximately 20 minutes).
– Serve with steamed jasmine rice, Asian greens (for example bok choy or choy sum) and fresh lime wedges.
