Tangy, pungent tamarind-soured fish broth with thick rice noodles, pineapple, herbs and shrimp paste — Penang's most iconic dish and one of the world's great noodle soups.
Penang assam laksa is one of Asia's most extraordinary noodle soups: a deeply sour, richly fragrant broth made from tamarind and mackerel, with the unique, pungent funk of hae ko (thick prawn paste) stirred in just before eating. Thick rice noodles are loaded with fresh mint, Vietnamese coriander (daun kesom), shredded cucumber, onion, pineapple and bird's-eye chillies, then drenched in the hot sour fish broth. The combination of sourness, fishiness, sweetness from the pineapple and the sharp heat of the chillies creates a flavour that is almost overwhelming — and utterly addictive. Penang assam laksa ranked number 7 on CNN Travel's list of the world's 50 most delicious foods, and once you taste it, the ranking seems conservative.
Serves 4
Simmer mackerel in water with lemongrass and galangal for 20 minutes. Remove fish, flake meat discarding bones and skin. Reserve broth.
Blend dried chillies and belacan to a paste. Fry in a little oil for 2 minutes. Add back to the reserved fish broth with tamarind paste, sugar and salt. Simmer for 15 minutes. Add flaked fish back to the broth.
Cook thick rice noodles according to package directions until tender. Drain and divide among bowls.
Ladle hot fish broth over the noodles. Top with pineapple, cucumber, onion and mint. Place a small spoonful of hae ko on top — guests stir it in themselves. Serve with extra chillies.
Hae ko (thick prawn paste) is the defining finishing touch — find it in Malaysian or Asian grocery stores.
The broth should be noticeably sour and savoury — adjust tamarind and salt to taste.
Daun kesom (Vietnamese coriander) is the authentic herb — substitute with a mix of mint and regular coriander.
Taste and adjust salt at the very end — flavors concentrate as liquids reduce, and a final pinch of flaky salt sharpens the whole dish.
Curry laksa (lemak) is a completely different coconut-based version — also Penang's other great laksa.
Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.
Spicier: add a finely chopped fresh chile or a teaspoon of crushed Aleppo/Urfa pepper to the aromatics for warm, layered heat instead of a single sharp hit.
Lighter: reduce the fat by a third and finish with a squeeze of citrus or a splash of vinegar to keep brightness without losing body.
Broth keeps refrigerated for 3 days. Store noodles and toppings separately. Assemble fresh.
Assam laksa is a uniquely Penang creation, developed by the island's Nyonya (Peranakan Chinese) community who blended Malay and Chinese culinary traditions. The word 'assam' means tamarind in Malay. The dish represents the multicultural character of Penang — a former British colonial port where Chinese, Malay, Indian and European food cultures mingled for centuries. Penang is now considered one of Asia's premier food destinations, with assam laksa at the centre of its culinary identity.
Hae ko (thick prawn paste) is sold in Malaysian and some Chinese grocery stores. It is thick and black, different from regular shrimp paste. Without it the dish loses an important flavour dimension — worth seeking out.
Yes — most of the components can be prepared up to a day in advance and refrigerated separately. Reheat gently and assemble just before serving so textures stay distinct.
Stay close to the role each ingredient plays: swap aromatics for similar ones (shallot for onion, lime for lemon), and keep the fat-acid-salt balance intact. Spice blends can usually be approximated with what's in the cupboard.
Authenticity sits on a spectrum — what matters more is honoring the technique and balance of flavors. If the dish tastes harmonious and respects how cooks in its home region would build it, you're on solid ground.
