Instructions

Step 1: Preparation of Ingredients

Begin by carefully preparing all your ingredients. First, wash the fresh produce thoroughly. Cut the tempeh into small cubes or thin slices depending on your preference. Cubed tempeh absorbs flavors better and provides a hearty bite, while slices are easier to eat with rice.

Next, prepare the spice paste: peel the shallots and garlic cloves. Using a mortar and pestle or a food processor, grind the shallots, garlic, candlenuts, black pepper, coriander, ginger, turmeric, and galangal until you achieve a smooth, aromatic paste. This step is crucial for developing the depth of flavor characteristic of authentic Indonesian cooking. If using a mortar and pestle, take your time to grind the ingredients thoroughly, pressing and crushing until the mixture becomes a homogeneous paste. In a food processor, pulse in short bursts to avoid over-processing.

Chop the tomato into small, manageable pieces. Slice the green onion thinly for garnishing later. Prepare the bird’s eye chilies by slicing them into rings or whole, depending on your spice tolerance.

Step 2: Sautéing the Spice Paste

Heat a large skillet or wok over medium heat. Add a tablespoon of cooking oil—vegetable or coconut oil works well—and allow it to heat up until shimmering. Carefully add the spice paste to the hot oil, stirring continuously to prevent burning. Sauté the paste for about 2–3 minutes until fragrant. This step releases essential oils and enhances the flavor profile of the dish.

Stir frequently to ensure even cooking, scraping the bottom of the pan to prevent sticking. The aroma of toasted spices will begin to fill your kitchen, signaling that you are on the right track. Be mindful not to burn the paste; adjust the heat as necessary.

Step 3: Incorporating Additional Aromatics

Add the sliced green onions and chopped tomatoes to the pan. Sauté for about a minute, stirring constantly, to soften the vegetables and incorporate their flavors into the spice mixture. Then, add the galangal, bird’s eye chilies, and any other optional aromatics. Continue cooking for another minute to allow the flavors to meld.

This stage builds the flavor base for the dish, ensuring that each bite is bursting with aromatic complexity.

Step 4: Cooking the Tempeh

Pour enough water into the pan to create a flavorful sauce. Typically, 1 to 1.5 cups of water suffice, but you can adjust based on the desired thickness of the sauce. Bring the water to a gentle boil over medium heat.

Once boiling, carefully add the prepared tempeh pieces into the pan. Gently stir to coat the tempeh with the spice mixture and sauce. Season with salt, sugar, and optional flavor enhancer, adjusting to taste. Add the soy sauce (kecap bango) to give the dish its characteristic sweetness and depth.

Lower the heat to simmer, ensuring a gentle bubbling. Cover the pan partially if necessary to prevent excessive evaporation. Allow the tempeh to cook for about 10–15 minutes, stirring occasionally, until the sauce thickens and the tempeh absorbs the flavors. The sauce should coat the tempeh nicely, and its richness will develop as it reduces.

Step 5: Final Adjustments and Serving

Once the sauce has reached your preferred consistency, taste the dish and adjust seasoning if needed. Add more salt or sugar depending on your palate. For a more intense flavor, let it simmer a few minutes longer, but be cautious not to over-reduce.

Turn off the heat and let the dish rest for a couple of minutes. This resting period allows the flavors to meld further, resulting in a more harmonious taste experience.

Garnish with sliced green onions or additional fresh herbs if desired. Serve hot alongside steamed rice, which complements the savory and sweet notes of the dish beautifully.

Preparation Tips

• Choosing the Right Tempeh: Opt for fresh, firm tempeh with a uniform color. The freshness directly influences flavor and texture.
• Grinding Aromatics: For a traditional touch, use a mortar and pestle to grind spices; it releases essential oils more effectively than a food processor, but both methods work well.
• Adjusting Spice Levels: Bird’s eye chilies add authentic heat. Adjust the quantity based on your spice tolerance. Remove seeds for milder flavor.
• Simmering: Slow simmering allows flavors to develop and the sauce to thicken naturally. Patience in this step yields the best results.
• Texture Variations: For a softer tempeh, cook longer; for a firmer bite, reduce cooking time slightly.

Nutritional Information

Tips and Tricks

• Use Fresh Ingredients: Fresh garlic, shallots, and spices make a noticeable difference in flavor.
• Control the Heat: Adjust bird’s eye chili quantity to suit your spice preference, and consider removing seeds for milder dishes.
• Enhance Umami: Adding a splash of fish sauce or mushroom soy sauce can deepen the umami flavor if not strictly vegetarian.
• Consistency Control: To thicken the sauce faster, increase heat slightly towards the end, but watch carefully to prevent burning.
• Leftovers: This dish tastes even better the next day as flavors meld. Store in an airtight container in the refrigerator for up to 3 days.

Add-ons

• Hard-boiled eggs, sliced, added at the end for extra protein.
• Tofu cubes, fried or steamed, as an alternative or addition to tempeh.
• Additional vegetables like bell peppers, carrots, or green beans for more color and nutrition.
• Fresh herbs such as cilantro or Thai basil for garnish.

Side Dishes

• Steamed jasmine or basmati rice to soak up the flavorful sauce.
• Indonesian sambal or chili paste for extra heat.
• Fried shallots or crispy garlic for garnish.
• Pickled vegetables for a contrasting tang.

Improvements

• Make it Spicy: Increase the number of bird’s eye chilies or add chili paste for more heat.
• Sweetness Adjustment: Use palm sugar or honey for a richer sweetness.
• Depth of Flavor: Roast the spices slightly before grinding to enhance aroma.
• Vegetarian Substitutes: Incorporate mushroom stock or miso paste for a deeper umami profile.

Save and Store

Allow the dish to cool completely before transferring to an airtight container. Store in the refrigerator for up to 3 days. To reheat, gently warm in a skillet over low heat, adding a splash of water or soy sauce if the sauce has thickened too much. Avoid freezing, as the texture of tempeh may change upon thawing.

FAQ

Can I make this dish vegan?

Yes, ensure you use a vegan-friendly soy sauce (without fish or animal derivatives) and check that no hidden animal products are included in flavor enhancers or seasonings.

Can I substitute tempeh with tofu?

Absolutely. Firm tofu can be used as a substitute. Press the tofu to remove excess moisture, then fry or bake before adding it to the sauce for added texture.

Is this dish spicy?

The traditional recipe uses bird’s eye chilies for authentic heat. Adjust the quantity based on your spice tolerance, or omit entirely for a milder flavor.

What are the best accompaniments?

Steamed rice is the classic pairing. You can also serve with vegetable stir-fries, sambal, or pickled vegetables for a complete meal.
