Instructions

1. Marinate the Fish

Start by preparing the sembilang fish. Rinse the fish pieces thoroughly under cold running water to remove any residual blood or impurities. Place the fish in a large bowl and squeeze fresh lime juice over the pieces, ensuring each piece is well coated with the citrus to enhance flavor and help reduce any fishy odor. Let the fish marinate for approximately 15 minutes. During this time, the acids in lime juice will help tenderize the fish and impart a subtle brightness to its flavor. After marination, rinse the fish gently under cold water, pat dry with paper towels, and set aside. Proper preparation of the fish ensures a tender, flavorful result and prevents the fish from breaking apart during cooking.

2. Prepare the Spice Paste

While the fish is marinating, focus on creating the aromatic spice paste, or bumbu halus. In a high-speed blender or food processor, combine the red curly chilies, shallots, garlic, candlenuts, ginger, and fresh turmeric. Blend until a smooth, fragrant paste forms—this may take about 1-2 minutes depending on your equipment. If the mixture is too thick or not blending smoothly, add a small amount of water or oil to facilitate blending. This spice paste acts as the flavor foundation of your gulai, releasing intense aroma and depth of flavor once cooked. For an authentic taste, do not skip the blending process or compromise on the quality of ingredients.

3. Sauté the Aromatics

Heat a generous amount of cooking oil—preferably coconut oil or vegetable oil—in a large wok or heavy-bottomed pot over medium heat. Once the oil is hot (around 160-180°C), add the blended spice paste. Stir continuously to prevent sticking and ensure even cooking. After about 2-3 minutes, add the bruised galangal, bruised lemongrass stalk, turmeric leaves, kaffir lime leaves, and bay leaves. Continue sautéing for approximately 5-7 minutes or until the mixture becomes fragrant, aromatic, and slightly darker in color. This step is crucial as it unlocks the full potential of the spices, releasing essential oils that form the backbone of the curry’s flavor profile. Stir occasionally to prevent burning, and adjust heat if necessary to maintain a gentle simmer.

4. Incorporate Coconut Milk and Simmer

Slowly pour in the coconut milk, stirring constantly to emulsify and prevent the mixture from curdling or separating. The addition of coconut milk provides a luscious, creamy base that balances the spices’ heat and aroma. Bring the mixture to a gentle boil over medium heat, stirring gently and continuously. The coconut milk will start to thicken and develop a rich texture, while the spices meld together. During this process, add the tamarind pieces, which will impart a subtle tang and complexity to the curry. Season with salt and a pinch of sugar—these help to enhance the overall flavor profile. Lower the heat to a simmer, and cook uncovered for about 15-20 minutes, allowing the flavors to deepen and the sauce to thicken slightly, resulting in a fragrant, flavorful curry base.

5. Add the Fish

Carefully introduce the marinated fish pieces into the simmering curry. Gently place them into the sauce, ensuring they are submerged but not broken apart. Cover the pot partially, and cook for approximately 10-15 minutes, or until the fish is tender and opaque. Avoid stirring vigorously at this stage to prevent the delicate fish from disintegrating. Instead, gently move the fish around with a ladle if needed. The fish will absorb the flavors of the curry, becoming tender and flavorful. The timing is crucial; overcooking can cause the fish to fall apart, while undercooking results in a less tender texture.

6. Add the Green Beans and Final Adjustments

About 2-3 minutes before serving, add the cut long green beans to the curry. They should remain bright green and slightly crisp to provide a fresh contrast to the rich sauce. Stir gently to incorporate, and cook until the green beans are tender but still retain their vibrant color. Taste the curry and adjust seasoning with additional salt or sugar if necessary. This step ensures a balanced flavor, with just enough sweetness and saltiness to complement the spices and coconut milk. Remove the turmeric leaves, bay leaves, and lemongrass stalks before serving as these are aromatic but not meant to be eaten.

7. Serve

Gulai Ikan Sembilang is best served hot, accompanied by steamed jasmine rice or coconut rice to soak up the flavorful sauce. Garnish with additional turmeric leaves or lime wedges for extra aroma and acidity, if desired. Serve family-style, allowing everyone to enjoy the rich, aromatic curry with a side of vegetables or traditional Indonesian condiments like sambal or acar (pickled vegetables). The dish pairs beautifully with simple side dishes that complement rather than overpower its complex flavors.

Preparation Tips

• Use Fresh Ingredients: Fresh turmeric leaves, kaffir lime leaves, and lemongrass significantly enhance the flavor. Always source high-quality, fresh seafood for the best results.
• Handling Fish: Clean and cut the fish properly, removing excess blood and scales. Marinating with lime helps improve flavor and texture.
• Adjusting Spice Levels: Customize the heat by increasing or decreasing the number of dried chilies. For milder versions, remove some seeds or opt for milder chilies.
• Simmer Gently: Maintain a gentle simmer to prevent fish from breaking apart and coconut milk from curdling.
• Flavor Balancing: Taste frequently and adjust salt and sugar to achieve a harmonious flavor profile.

Nutritional Information

Tips and Tricks

• Make Ahead: Prepare the spice paste in advance and store it in an airtight container in the refrigerator for up to 3 days. This reduces preparation time and allows flavors to meld.
• Use Coconut Milk Cans: Opt for full-fat canned coconut milk for a richer, creamier curry. Shake the can well before use to ensure consistency.
• Layer Flavors: Toast candlenuts before blending to enhance their flavor and improve the spice paste’s texture.
• Cooking Fish: Add the fish towards the end to prevent overcooking and falling apart, especially for delicate fish varieties.
• Presentation: Garnish with fresh herbs or additional turmeric leaves for an authentic look and enhanced aroma.

Add-ons

• Fried tempeh or tofu for added protein
• Hard-boiled eggs, sliced for extra richness
• Fresh herbs like cilantro or basil for garnish
• Sambal or spicy chili paste for extra heat
• Pickled vegetables or acar for tangy contrast

Side Dishes

• Steamed jasmine or coconut rice
• Indonesian-style vegetables like stir-fried kangkung (water spinach)
• Fried plantains or crispy prawn crackers for texture
• Simple vegetable salads with lime dressing

Improvements

• Incorporate additional herbs such as Thai basil or mint for a fresh twist.
• Add a splash of tamarind or lime juice at the end for extra acidity.
• Use different types of fish such as snapper or tilapia to vary the flavor profile.
• Experiment with spice intensity by adjusting chili quantities.
• Introduce vegetables like eggplant or bell peppers for more texture and color.

Save and Store

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently over low heat, adding a splash of coconut milk or water if necessary to restore the sauce’s consistency. For longer storage, freeze in portions for up to 2 weeks. Thaw in the refrigerator overnight before reheating. To maintain optimal flavor and texture, avoid freezing fish directly as it may alter the delicate texture.
