Instructions

Step 1: Preparing the Spice Paste

Begin by assembling your fresh ingredients for the spice paste. Peel the shallots and garlic; if you have fresh turmeric, galangal, and ginger, peel them carefully using a sharp knife or a vegetable peeler. Measure the candlenuts, and chop the lemongrass stalks into smaller pieces for easier blending. Place all these ingredients into a food processor or mortar and pestle. Blend or grind until you achieve a smooth, fragrant paste. This process releases the essential oils and flavors, forming the aromatic backbone for your gulai. If using a mortar and pestle, take your time to grind the ingredients thoroughly, pressing and turning to develop a fine, uniform paste. For a smoother consistency, add a splash of water during blending, but avoid making it too watery. The spice paste should be aromatic, slightly oily, and well-blended, with visible flecks of herbs and spices.

Step 2: Sautéing the Spice Paste

Heat a large, heavy-bottomed pot or deep skillet over medium heat. Add about 2-3 tablespoons of cooking oil—preferably coconut oil for authenticity or vegetable oil if unavailable. When the oil is hot, carefully add the spice paste. Stir constantly using a spatula or wooden spoon to prevent sticking and burning. Sauté for approximately 5-7 minutes, or until the paste releases a rich aroma and turns a shade darker golden brown. This step is crucial as it develops the deep flavors that will infuse the entire dish. Be attentive to the heat level; too high can burn the spices, while too low may prolong the cooking process. Maintain gentle simmering, stirring regularly to ensure even cooking and prevent scorching. The spice paste will thicken, become fragrant, and start to stick to the bottom of the pan—indicating it’s ready for the next step.

Step 3: Infusing Aromatic Leaves

Add the kaffir lime leaves, bay leaves, and turmeric leaf into the sautéed spice mixture. Stir gently to incorporate these fragrant leaves, allowing their oils and aromas to meld with the spice base. Continue cooking for another 2-3 minutes, which will enhance the dish’s depth and complexity. The kaffir lime leaves contribute a citrusy aroma, while the bay leaves add subtle earthiness. The turmeric leaf imparts a mild, fresh turmeric flavor, elevating the overall profile of the curry. These leaves are essential for authentic flavor, so do not omit them. If fresh turmeric leaves are unavailable, you may substitute with dried turmeric powder, but fresh leaves lend a more vibrant aroma.

Step 4: Creating the Broth Base

Pour water into the pot, gradually adding approximately 500 ml or enough to create a broth-like consistency. Stir the mixture to combine all flavors, then bring it to a gentle simmer. Adjust the amount of water based on your preferred soupiness—less water results in a thicker curry, while more creates a lighter broth. Cover the pot partially to retain heat and aroma. Let the broth simmer for about 10 minutes, allowing the spices and leaves to infuse thoroughly into the water, creating a fragrant and flavorful base for the tuna head.

Step 5: Adding the Long Beans or Cassava Leaves

Introduce the long beans or cassava leaves into the simmering broth. If using long beans, cut them into manageable lengths—about 4-5 inches each—to ensure even cooking. Add them carefully, stirring gently to distribute evenly. Cook for approximately 5 minutes, until they start to soften but retain some bite. If using cassava leaves, ensure they are prepared properly—washed and chopped—before adding. These greens lend a fresh, slightly bitter flavor that balances the richness of the coconut milk and spices. Their presence adds texture, color, and nutritional value to the dish.

Step 6: Incorporating the Tuna Head

Gently place the halved tuna head into the simmering broth. Carefully lower it into the pot, ensuring the cut side is facing down for better flavor absorption. Using a spoon, ladle some of the fragrant broth over the fish head to help it absorb the spices and flavors. Reduce the heat slightly, maintaining a gentle simmer, and cook for about 10 minutes. During this time, the fish head will release its flavor into the broth, enriching it further. Handle the fish with care—avoid vigorous stirring—to prevent breaking apart the delicate flesh. The tuna head should be cooked through, tender, and infused with the aromatic spice broth.

Step 7: Adding Coconut Milk

Gradually pour the coconut milk into the pot, stirring continuously to prevent curdling or separation. Coconut milk adds richness and a creamy texture to the gulai, balancing the spices’ heat and aromatic intensity. Once all the coconut milk is added, bring the mixture back to a gentle simmer. Continue cooking for an additional 10-15 minutes, allowing the flavors to meld and deepen. During this stage, the oil from the coconut milk will start to separate slightly from the broth, indicating the dish is nearing readiness. Keep the heat moderate and avoid boiling vigorously to preserve the coconut milk’s smooth, velvety texture.

Step 8: Final Seasoning and Garnishing

Taste the gulai and adjust the seasoning to your preference. Add salt, sugar, and black pepper gradually, balancing the savory, sweet, and spicy notes. Remember that the salt enhances the dish’s depth, while a touch of sugar can mellow the spice and acidity. If desired, garnish with additional long beans, fresh herbs, or sliced chilies for extra color and flavor. Serve hot, accompanied by steamed jasmine rice or rice noodles, allowing the rich, spicy coconut broth to complement the neutral rice base.

Preparation Tips

• Choosing the right tuna head: Freshness is key. Look for a bright color, firm flesh, and a mild ocean scent. Ask your fishmonger to prepare the head by halving and washing it thoroughly with lime or lemon juice to remove any residual blood or impurities.
• Handling the spice paste: For a more intense flavor, toast the candlenuts lightly before blending. Toasting enhances their nutty aroma and flavor. If you prefer a milder dish, you can reduce the amount of candlenuts or omit them altogether.
• Cooking the fish head: Be gentle when placing the tuna head into the broth to prevent breaking the flesh. Use a slotted spoon or ladle to handle the fish carefully.
• Adjusting spice levels: For those who prefer milder flavors, reduce or omit the black pepper and chili ingredients. Conversely, add sliced fresh chilies or chili paste for extra heat.

Tips and Tricks

• Enhance aroma: Add a few slices of fresh lime or lemon zest during the final simmer for a citrusy boost.
• Make ahead: Prepare the spice paste and sauce base a day in advance; store them in airtight containers in the refrigerator for convenience.
• Vegetarian variation: Substitute the tuna head with firm tofu or tempeh to create a vegetarian-friendly version of the dish.
• Adjust consistency: If the curry becomes too thick, add a little hot water or coconut milk to loosen it. For a thicker stew, simmer uncovered to reduce the liquid.

Add-ons

• Hard-boiled eggs—boiled separately and added at the end for extra protein and richness.
• Fried shallots or crispy garlic as garnish for added texture.
• Freshly sliced red chilies or bird’s eye chilies for heat.
• Additional herbs like cilantro or Thai basil for garnish and freshness.

Side Dishes

• Steamed jasmine rice or coconut rice to soak up the flavorful broth.
• Sautéed vegetables like bok choy, spinach, or kangkung.
• Indonesian-style sambal or chili sambal for extra heat.
• Pickled vegetables or acar for a tangy contrast.

Improvements

• Use a slow cooker for a more tender, flavor-infused result—set on low for 4-6 hours.
• Incorporate additional spices like turmeric powder, coriander, or cumin to deepen the flavor profile.
• Experiment with different greens or vegetables to vary texture and taste.
• Finish with a splash of lime juice or tamarind extract for added brightness.

Save and Store

Allow the dish to cool completely before transferring to airtight containers. Store in the refrigerator for up to 2 days. Reheat gently over low heat, stirring occasionally, to preserve the coconut milk’s texture. The flavors tend to deepen overnight, making leftovers even more delicious.

FAQ

Can I use canned tuna instead of a tuna head?

While canned tuna can be used for a quicker version, it will lack the richness and depth of flavor from the tuna head. The traditional dish relies on the head’s bones and cartilage to develop a complex broth. However, for convenience, canned tuna can be added towards the end to boost protein.

What if I cannot find candlenuts?

Candlenuts are a key ingredient for their nutty aroma and thickening properties. If unavailable, substitute with macadamia nuts or blanched almonds in small amounts, or omit entirely, adjusting seasoning accordingly.

Can I make this dish vegetarian?

Yes, replace the tuna head with firm tofu or tempeh, and use vegetable broth instead of water. Add extra vegetables like eggplant, mushrooms, or carrots for added flavor and texture.

How do I know when the tuna head is fully cooked?

The fish head should be tender and the flesh easily coming away from the bones. The internal temperature should reach at least 145°F (63°C). The broth should be fragrant, and the fish should be opaque and flaky.
