Instructions

Step 1: Preparation of Jengkol

Start by preparing the jengkol beans, which are known for their strong aroma and unique flavor. Proper preparation is crucial to reduce pungency and ensure tender, flavorful beans. Begin by heating a sufficient amount of oil in a deep frying pan over medium heat. Once the oil is hot—ideally around 170°C (340°F)—carefully add the jengkol beans. Fry them until they are cooked through, which typically takes about 8-10 minutes, stirring occasionally to prevent sticking or burning.

Fried jengkol should turn a light golden brown and develop a slightly crispy exterior. Once done, use a slotted spoon to remove the jengkol from the oil and transfer them into a bowl of cold water. This step helps to halt the cooking process and makes peeling easier. Allow the jengkol to soak for about 10 minutes, then gently crush each bean using a pestle or the back of a spoon while peeling off the outer skin. Discard the skins and set the cleaned jengkol aside for later use.

Step 2: Cooking the Mackerel

In the same pan used for frying the jengkol, add a little more oil if necessary and heat over medium heat. Carefully fry the mackerel until they are just cooked through—about 4-5 minutes per side—until the flesh is opaque and flakes easily. For a more intense flavor, you can fry the mackerel until golden brown on the outside, but this is optional and depends on your preference. Once cooked, remove the fish from the pan and set aside. You may also choose to fry the mackerel only partially if you prefer a softer texture in the final dish, as they will continue to cook in the simmering stage.

Step 3: Making the Spice Paste

Place the red chilies, garlic, shallots, candlenuts, ginger, and turmeric into a blender or food processor. Blend until a smooth, homogeneous paste forms. If the mixture is too thick, add a small amount of water or oil to facilitate blending. The spice paste is the flavor backbone of the gulai, imparting heat, aroma, and depth. For those seeking a milder version, reduce the number of chilies accordingly or remove the seeds to lessen spiciness.

Step 4: Preparing the Gulai Base

In a large, heavy-bottomed pot, pour in the coconut milk and turn the heat to medium. Add the bay leaves, bruised lemongrass stalk, tamarind fruit (or tamarind paste), and the freshly blended spice paste. Stir thoroughly to combine all ingredients and bring the mixture to a gentle boil. As the coconut milk heats, it will release fragrant aromas that evoke the essence of Indonesian cooking. Keep a close eye to prevent the coconut milk from boiling over or curdling.

Step 5: Simmering the Dish

Once boiling, reduce the heat to low to maintain a gentle simmer. Add the fried jengkol beans into the pot, followed by the fried mackerel. Stir gently to coat everything evenly with the aromatic gravy. During this simmering process, flavors will meld, and the coconut milk will thicken slightly, developing a rich, velvety texture. Allow the dish to cook uncovered for approximately 30-40 minutes, stirring occasionally to prevent sticking or burning at the bottom.

Adjust the seasoning by tasting the gravy and adding more salt or seasoning as necessary. If the gravy thickens too much during simmering, you may add a splash of warm coconut milk or water to achieve your desired consistency. For a tangier flavor, add additional tamarind or lime juice just before serving.

Preparation Tips

• Peeling Jengkol: The peeling process is crucial to reduce the characteristic smell and improve texture. Using cold water after frying helps to loosen the skins, making peeling easier. Alternatively, soaking jengkol in salted water overnight can also help reduce pungency.
• Frying Techniques: Fry jengkol and mackerel separately to control cooking times and prevent flavor transfer. Ensure oil is hot enough to achieve crispy, tender beans without absorbing excess oil.
• Spice Paste Variations: For a more complex flavor, add aromatics like turmeric or galangal during blending. You can also include lemongrass and kaffir lime leaves for added fragrance.
• Cooking Coconut Milk: Always stir the coconut milk gently during simmering to prevent curdling. Use a low to medium heat for best results.
• Adjusting Spice Level: To cater to different spice tolerances, vary the number of chilies or include milder alternatives such as bell peppers or roasted chilies.

Nutritional Information

Tips and Tricks

• Flavor Enhancement: Toast the candlenuts and spices lightly before blending for a deeper flavor profile.
• Freshness Counts: Use fresh herbs and ingredients whenever possible to maximize aroma and taste.
• Cooking Time: Longer simmering enhances flavor complexity; however, avoid overcooking the mackerel to prevent it from falling apart.
• Alternative Proteins: Substitute mackerel with other oily fish like sardines or tuna, or use tofu for a vegetarian version.
• Presentation: Garnish with chopped fresh herbs or a squeeze of lime for added freshness.

Add-ons

• Chopped fresh coriander or basil
• Fried shallots or garlic chips
• Sliced red chili for extra heat
• Lime wedges for a tangy finish

Side Dishes

• Steamed jasmine rice or coconut rice
• Indonesian vegetable sambal ulek
• Pickled vegetables (acar)
• Simple sautéed greens like kangkung or bok choy

Improvements

• Introduce roasted spices for a smoky flavor
• Incorporate tamarind paste or lime juice at the end for a brighter acidity
• Use homemade coconut milk for richer flavor
• Experiment with additional spices like coriander or cumin for variation

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 to maintain the gravy’s consistency. For longer storage, freeze the dish in portions—preferably without the fish, which is best consumed fresh—and reheat thoroughly before serving.

Frequently Asked Questions (FAQ)

Can I skip the frying step for jengkol?

Frying enhances the flavor and reduces pungency, but if you prefer a healthier version, you can boil the jengkol instead. Boiled jengkol will need to be soaked in salted water beforehand to lessen odor.

Is mackerel necessary, or can I use other fish?

Mackerel is traditional because of its rich, oily flesh, which complements the coconut gravy. However, you can substitute with other oily fish like sardines or skip fish altogether for a vegetarian variation.

How do I handle the strong smell of jengkol?

Proper preparation with soaking, boiling, and peeling significantly reduces the pungency. Cooking with aromatics like ginger and turmeric also helps mask residual odors.

What is the best way to serve this dish?

Serve hot, accompanied by steamed rice and fresh side dishes. Garnish with herbs or a squeeze of lime for added brightness.
