Method
- Poach the mackerel in 2L water for 8 minutes until just cooked. Lift out, debone carefully, flake the flesh and reserve. Strain and reserve the poaching liquid as fish stock.
- Blend soaked chilies, shallots, garlic, turmeric, galangal, lemongrass and belacan to a smooth paste with a splash of stock.
- In a heavy pot, fry the spice paste in 3 tbsp oil for 8 minutes until fragrant and the colour deepens. Add the fish stock, asam keping, half the torch ginger flower and half the laksa leaves.
- Simmer 30 minutes uncovered — the broth should reduce slightly, the asam keping releasing tannins and souring the soup. Add tamarind paste, palm sugar and salt. Taste — sour first, then sweet, savoury, with a chili build.
- Return half the flaked fish to the broth and simmer 5 more minutes; the fish disintegrates and thickens the soup. Reserve the rest of the fish for topping bowls.
- Cook noodles in unsalted boiling water for 4 minutes; drain. Divide into deep bowls. Ladle the hot broth over generously. Top each bowl with reserved fish, pineapple, cucumber, sliced red onion, the rest of the torch ginger flower, and laksa leaves. Serve with hae ko (sweet shrimp paste sauce) at the table for each diner to drizzle.

Cultural Note
Penang asam laksa was crowned by CNN in 2011 as one of the world's top ten dishes — a controversial assertion that the Penang heritage stalls promptly hung as banners. The 'laksa' name applies to a category, not a single dish: Penang asam laksa (sour fish-tamarind), Sarawak laksa (sambal-and-coconut), curry laksa (Nyonya, with curry paste and coconut). Each Malaysian region claims theirs is the original. The torch ginger flower and laksa leaves are non-substitutable; without them, you have a tamarind fish soup, not asam laksa.
