What Is Otak Otak?
Otak Otak is a seasoned fish paste blended with a fragrant mix of herbs, spices, and coconut milk, then wrapped in banana leaves and cooked over hot coals or steamed.
The name, which loosely translates to “brains” in Malay, is a playful reference to the dish’s soft texture rather than its ingredients. It is silky, aromatic, and deeply flavourful, with each mouthful carrying hints of lemongrass, chilli, and the earthiness of turmeric.
You’ll find Otak Otak in various forms across Malaysia, particularly in Johor and Penang. Some versions are fiery with heat, others more subtle and creamy. It is commonly sold at food markets, roadside stalls, and restaurants alike, often paired with rice or served on its own as a savoury bite. The preparation may seem humble, but the flavours are anything but.
Ingredients and Taste
The heart of Otak Otak lies in the fish, typically mackerel, though other firm white fish can be used. The fillets are blended into a paste with coconut milk, eggs, and rice flour, creating that smooth custard like texture.
What sets Otak Otak apart, however, is the spice blend. Aromatic herbs like lemongrass and galangal, along with chillies, shallots, garlic, and turmeric, are ground into a vibrant paste that infuses the fish mixture with layers of complexity.
Wrapped in banana leaves, the mixture is grilled until the edges are slightly charred, releasing a smoky fragrance that hints at what’s inside. The texture is tender and almost creamy, with a soft heat that lingers gently rather than overwhelming the palate.
The richness of coconut milk balances the punch of the spices, while the banana leaf imparts a subtle earthiness. Each element contributes to a dish that feels both rustic and refined.
A Taste of History
Otak Otak’s origins are as layered as its flavours. While it is now deeply rooted in Malaysian cuisine, it shares culinary ties with Indonesian and Thai coastal regions, reflecting the fluid cultural borders of Southeast Asia’s maritime trade routes.
The dish is believed to have evolved through centuries of cultural blending, particularly among the Peranakan communities, who combined local Malay ingredients with Chinese culinary techniques.
In Malaysia, it became particularly popular in Johor and along the west coast, where fresh fish and tropical herbs are plentiful. The use of banana leaves as a cooking vessel is both practical and traditional, tracing back to indigenous cooking practices that valued natural materials and open fire cooking.
Today, Otak Otak remains a cherished dish, enjoyed across generations and regions. Its popularity endures not just for its unique taste, but for the way it captures the essence of Malaysian food culture: bold, diverse, and full of heart.
Malaysian Otak Otak (Spiced Fish custard)
Ingredients
For the fish custard:
- 400 g mackerel fillet skinless and boneless (or other firm white fish)
- 150 ml thick coconut milk
- 1 large egg
- 1 tbsp cornflour
- 1 tsp salt
- 1 tsp sugar
- 1 kaffir lime leaf finely sliced
- 10 banana leaves cut into 20cm x 15cm pieces, softened over flame or in boiling water
For the spice paste:
- 4 dried red chillies soaked in hot water until soft
- 2 fresh red chillies
- 4 shallots
- 2 cloves garlic
- 2 stalks lemongrass white part only, thinly sliced
- 2 cm piece galangal
- 1 cm piece fresh turmeric or 1 tsp turmeric powder
- 1 tsp belacan fermented shrimp paste, toasted
- 2 tbsp vegetable oil for blending
Instructions
- To begin, prepare the spice paste. Blend the soaked dried chillies, fresh chillies, shallots, garlic, lemongrass, galangal, turmeric, belacan, and oil into a smooth paste. Use short pulses and scrape the sides to ensure even blending. If needed, add a splash of water to ease the blending process.
- Heat a small pan over medium heat and sauté the blended spice paste for 5–7 minutes, stirring constantly, until fragrant and the oil begins to separate. This step deepens the flavour of the paste and removes any rawness from the spices. Set aside to cool.
- Meanwhile, cut the fish into small chunks and pulse in a food processor until a coarse paste forms. Avoid over processing; the custard should have texture. Alternatively, pound with a pestle for a more traditional texture.
- In a large mixing bowl, combine the fish paste with the cooled spice paste, coconut milk, egg, cornflour, salt, sugar, and finely sliced kaffir lime leaf. Mix thoroughly with a spoon or your hands until well incorporated and the mixture is smooth yet slightly firm.
- Prepare your banana leaves by softening them briefly over an open flame or in hot water. This step prevents tearing and makes folding easier. Wipe each leaf clean before use.
- Scoop about 2 heaped tablespoons of the fish mixture onto the centre of each banana leaf. Fold the leaf lengthwise over the mixture, then tuck in the sides to form a small parcel. Secure with toothpicks if necessary. Repeat with the remaining mixture and leaves.
- Set up a steamer over medium heat. Once the water is boiling, place the parcels in a single layer in the steamer basket. Steam for 15–20 minutes, or until the custard is firm and fully cooked through. Avoid overcrowding to allow even cooking.
- Once steamed, you may serve the Otak Otak as is, or for added depth, grill the parcels over hot coals or a grill pan for 1–2 minutes per side. This introduces a smoky aroma and lightly chars the banana leaf, enhancing the dish’s complexity.
- To serve, gently open each parcel at the table to release the fragrant steam. Garnish with additional slivers of kaffir lime leaf if desired. Otak Otak is best enjoyed warm, accompanied by plain rice, nasi lemak, or as a standalone snack with sambal on the side
