Khanom Chin Nam Ya (Rice Noodles with Fish Curry Sauce)

Ingredients

• For the nam ya paste
• 30 g galangal, peeled, roughly chopped
• 2 stalks lemongrass, outer leaves removed, thinly sliced
• 1 tsp kaffir lime zest, finely grated
• 20 g fresh turmeric, peeled, roughly chopped
• 5 dried chillies, soaked in water until softened, drained
• 1 tsp shrimp paste (kapi), roasted in foil
• 30 g krachai (fingerroot / Chinese keys), peeled, roughly chopped
• For the sauce
• 400 ml coconut milk
• 400 g firm white fish (e.g. mackerel, snakehead, or similar), skin and bones removed after cooking
• 2 tbsp fish sauce (nam pla), to taste
• 1 tsp palm sugar, or to taste
• 1 tbsp lime juice, to taste
• For the noodles
• 400 g khanom chin (fermented fresh round rice noodles), room temperature
• For the accompaniments
• 100 g bean sprouts, blanched briefly, drained
• 100 g long beans, cut into 3 cm lengths, blanched
• 1 cucumber, thinly sliced
• 1 small bunch Thai sweet basil, leaves picked
• 4 kaffir lime leaves, central rib removed, very finely sliced in chiffonade
• 4 eggs, hard-boiled and peeled

Method

1. 1
   Place the dried chillies in a mortar and pound to a rough paste, starting with them alone so their tough skins break down fully before the wetter ingredients are added and turn everything slippery. Add the galangal, lemongrass, and kaffir lime zest in sequence, pounding each to a paste before adding the next, so each fibrous ingredient is fully surrendered before the next complicates the work. Add the krachai and fresh turmeric and continue pounding, then work in the shrimp paste last — the finished paste should be smooth, dense, and deeply fragrant, earthy and medicinal from the krachai and turmeric, with no visible fibrous threads remaining.
2. 2
   Bring the coconut milk to a gentle simmer in a heavy pan over medium heat — a hard boil will cause the fat to split and leave a greasy, grainy sauce rather than a unified one. Add the nam ya paste and stir to combine, then poach the fish in this liquid, turning once, until the flesh is fully cooked through and beginning to break apart. The coconut milk will deepen to a yellow-orange from the turmeric and carry a persistent, pungent aroma.
3. 3
   Lift the fish from the pan, remove all skin and bones, then return the flesh to the pan and mash it thoroughly into the sauce using a spoon or pestle until no discrete flakes remain — the fish is not a garnish but the structural body of the sauce, and any visible chunks will betray the defining character of nam ya. This is where the dish lives or dies: an incompletely mashed sauce will have the wrong texture and cannot be recovered once the noodles are dressed. The result should be a thick, unified sauce in which flesh and coconut milk are indistinguishable.
4. 4
   Adjust the sauce for the four-flavour balance: season with fish sauce for salt, palm sugar for sweetness, and lime juice for sourness, tasting repeatedly so no single flavour dominates and each sharpens the others into a full, pungent whole. Add a little water or additional coconut milk if the sauce is too thick to pour in a slow ribbon, since a sauce that sits in a solid mass on the noodles will not coat them evenly. Set aside; the sauce is served at room temperature or slightly warm, not hot.
5. 5
   Arrange the khanom chin noodles in loose nests in each bowl, leaving them at room temperature so their slight sourness from fermentation remains present and lifts the richness of the sauce rather than being muted by heat. Ladle the nam ya sauce generously over the noodles, then serve the blanched bean sprouts, long beans, sliced cucumber, sweet basil leaves, and kaffir lime leaf chiffonade alongside so each diner can temper the sauce with fresh, cooling bite. Place one hard-boiled egg beside each portion; the bowl is complete when the sauce is visible pooling around the noodles and the accompaniments retain their fresh colour.
