Ingredients

Instructions

Preparation of the Fish

Start by cleaning the ikan kakap thoroughly under cold running water. Remove any scales, gills, and entrails if present. Pat the fish dry with paper towels. Using a sharp chef’s knife, cut the fish into 4 to 6 pieces, depending on their size and your preference for serving portions. For a more elegant presentation, you may choose to keep the fish whole, but cutting into manageable pieces allows better flavor absorption and easier eating. Set aside the fish pieces on a clean plate.

Sautéing the Aromatics

Place a medium-sized pot on the stove over medium heat. Add 2 tablespoons of cooking oil, allowing it to heat up until shimmering but not smoking. Once hot, add the sliced shallots, minced garlic, and sliced chilies (both red and green curly varieties). Stir continuously using a wooden spoon or spatula, cooking until the shallots become translucent and the mixture releases a fragrant aroma. This process should take approximately 2 to 3 minutes. Be attentive to avoid burning the garlic or shallots, as this can impart a bitter taste to your soup.

Adding Herbs and Aromatic Foundations

Next, add the bruised lemongrass stalk, kaffir lime leaves, and bay leaves to the sautéed aromatics. Bruising the lemongrass releases more essential oils, contributing a fresh, citrusy aroma to the broth. Stir the mixture gently, allowing the herbs to release their fragrant oils. This process should take about 1 minute, during which you will notice an intensified aroma filling your kitchen. These herbs form the aromatic backbone of Sup Ikan Kakap, giving it that quintessential Southeast Asian flavor profile.

Building the Broth

Pour 1 liter of water into the pot, ensuring the ingredients are submerged. Increase the heat to bring the mixture to a gentle boil. Once boiling, reduce the heat to maintain a simmer. Allow the broth to simmer for approximately 5 minutes, enabling the flavors of the herbs and aromatics to meld into the water. During this time, you can prepare additional ingredients or clean your workspace.

Introducing the Citrus and Seasonings

Squeeze the juice from one lime directly into the broth, making sure to filter out any seeds. The lime juice adds brightness and balances the richness of the fish. Taste the broth and adjust acidity if needed, adding more lime juice for extra tanginess. Add a pinch of sugar and salt to enhance the overall flavor profile—start with 1 teaspoon of salt and 1/2 teaspoon of sugar, then adjust according to your taste preferences.

Adding the Fish and Tomato

Gently place the fish pieces into the simmering broth, being careful not to break the delicate flesh. Add the diced tomato to introduce a natural sweetness and acidity, complementing the lime’s brightness. Allow the soup to simmer gently for about 8-10 minutes, or until the fish is cooked through and opaque. During this process, avoid stirring too vigorously to prevent the fish from breaking apart. The fish will absorb the flavors of the broth, becoming tender and flavorful.

Final Touches

In the last minute of cooking, add the sliced spring onions and fresh basil leaves. The heat will wilt the basil slightly, releasing its aromatic oils into the soup. Taste again and adjust seasoning as needed, adding more salt, lime juice, or chili if you prefer more heat. Remove the lemongrass, bay leaves, and kaffir lime leaves if you prefer a clearer broth, or leave them in for a more rustic presentation.

Serving

Carefully ladle the hot Sup Ikan Kakap into individual bowls, ensuring each serving contains a generous amount of fish, broth, and herbs. Serve immediately while hot, accompanied by steamed jasmine rice or crusty bread for a complete meal. For an authentic Indonesian experience, serve with a side of sambal or sliced fresh chili for those who enjoy extra spice.

Preparation Tips

• Choose fresh, high-quality ikan kakap for maximum flavor and tenderness. Fresh fish should have clear eyes, firm flesh, and a clean smell.
• Bruising the lemongrass enhances its aroma; use the back of a knife or a mortar and pestle to gently crush it.
• Adjust the level of spiciness by varying the amount of bird’s eye chilies—add more for heat or omit for milder taste.
• If you prefer a clearer broth, remove the herbs after simmering, or strain the soup through a fine sieve before serving.
• For a more nutrient-rich broth, add sliced carrots or other root vegetables during simmering.

Tips and Tricks

• Use fresh herbs and fish for the best flavor. Frozen fish can be used but may result in a slightly different texture.
• Adjust the level of spice by increasing or decreasing the number of bird’s eye chilies. Always taste as you go.
• Adding a splash of coconut milk can create a richer, creamier version if desired, though traditional Sup Ikan Kakap is usually clear.
• For a more aromatic broth, toast the dried spices briefly before adding water.
• Ensure not to overcook the fish to maintain its tenderness and prevent it from falling apart.

Add-ons

• Sliced boiled eggs
• Crushed peanuts for added texture
• Additional fresh herbs like cilantro or Thai basil
• Chopped chili oil drizzle for extra heat
• Steamed jasmine rice or rice noodles

Side Dishes

• Steamed jasmine rice (recommended for a complete meal)
• Indonesian sambal (spicy chili paste) for added flavor
• Fresh vegetable platter with cucumber, lettuce, and pickled vegetables
• Fried tempeh or tofu

Improvements

• Introduce additional aromatic ingredients like galangal or turmeric for variations.
• Use homemade fish stock instead of water for deeper flavor.
• Add a dash of fish sauce or soy sauce for umami enhancement.
• Experiment with different herbs such as coriander or mint for unique twists.
• Include vegetables like bok choy or spinach for added nutrients and color.

Save and Store

This soup is best enjoyed fresh, but if needed, store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove over low heat, avoiding boiling to prevent the fish from overcooking or disintegrating. Do not freeze, as fish texture may change upon thawing.

FAQ

Can I use other types of fish?

Yes, firm white fish such as tilapia, grouper, or sea bass can replace ikan kakap. Ensure the fish is fresh and suitable for quick cooking.

Is this dish spicy?

The dish can be made mild or spicy depending on the amount and type of chilies used. Bird’s eye chilies add significant heat, so adjust accordingly.

Can I make this soup vegetarian?

Traditional Sup Ikan Kakap relies on fish, but you can substitute fish with tofu and vegetable broth for a vegetarian version, adding more herbs and vegetables for flavor.
