Ingredients

Instructions

Step 1: Prepare the Spice Paste

Begin by carefully peeling the shallots and garlic cloves. To achieve the ideal consistency, finely chop or grind these ingredients. Using a mortar and pestle is traditional, as it releases the essential oils and enhances flavor; however, a food processor can also be employed for convenience. Place the shallots, garlic, curly red chilies, half of the tomato, and salt into your mortar or food processor. Grind or pulse until you obtain a smooth, aromatic paste. The texture should be fine and well-integrated, with no large chunks remaining. This step is crucial because it ensures the spice blend will evenly coat the ingredients and release maximum flavor during sautéing.

Step 2: Sauté the Spice Paste

Heat approximately one tablespoon of cooking oil (preferably vegetable or canola oil for neutral flavor) in a large wok or deep skillet over medium heat. When the oil is hot but not smoking, add the prepared spice paste. Stir continuously using a spatula or wooden spoon to prevent sticking and burning. The paste will initially bubble and release a fragrant aroma within 1-2 minutes. Continue to cook, stirring constantly, until the mixture darkens slightly and becomes more fragrant, approximately 3-4 minutes. This process is called ‘bumbu tumis’ in Indonesian cuisine and is essential for building the depth of flavor in the dish.

Step 3: Incorporate Water and Simmer

Once the spice paste has cooked to a fragrant stage, carefully pour in the 100 cc of water. Stir well to combine, loosening any bits stuck to the pan’s surface. Allow the mixture to simmer gently for about a minute, which helps meld the flavors and creates a light sauce base for the vegetables. This step also helps to soften the spice paste further, making it more palatable and evenly distributed throughout the dish.

Step 4: Add Kangkung and Seasoning

Next, add the kangkung (water spinach) into the pan. It is best to hold the bunch by the stems and chop into manageable sections if desired, but whole leaves can also be used. Toss the kangkung gently in the spice mixture, ensuring it is coated evenly. Add oyster sauce to taste; start with approximately 1-2 tablespoons, and adjust according to preference. Additionally, sprinkle in the flavor enhancer, if used, to boost umami. Continue to stir-fry, allowing the kangkung to wilt and become bright green, which typically takes about 3-5 minutes. During this process, taste the seasoning and add more oyster sauce or salt if necessary.

Step 5: Finish with Tempeh

Finally, add the thin slices of tempeh to the wok. Gently fold them into the stir-fry, being careful not to break them apart. The tempeh will absorb the flavors from the spice paste and sauces, enhancing its nutty, fermented taste. Cook for an additional 2 minutes, just enough to heat the tempeh through and allow its surface to slightly crisp up if desired. The dish is now ready to be served.

Step 6: Serve

Transfer the Tumis Kangkung Sambal Tempe to serving dishes. It can be enjoyed immediately while warm. This dish pairs beautifully with steamed jasmine rice or can be served as part of a larger Indonesian meal with other vegetable, seafood, or meat dishes. Garnish with fresh chopped chili or fried shallots for added flavor and visual appeal.

Preparation Tips

• Use fresh kangkung for the best texture and flavor; look for vibrant green leaves with firm stems.
• Adjust the spice level by adding more or fewer red chilies based on your heat tolerance.
• If you prefer a richer flavor, add a splash of fish sauce or soy sauce during seasoning.
• For a vegan version, substitute oyster sauce with mushroom sauce or a soy-based alternative.
• Ensure the tempeh slices are thin to allow quick absorption of flavors and even heating.

Nutritional Information

Tips and Tricks

• Use a high-quality oyster sauce for richer flavor; brands vary in saltiness and sweetness, so taste and adjust accordingly.
• Pre-wash and dry the kangkung thoroughly to prevent excess water during stir-frying.
• Chop the chilies finely or leave them whole depending on the desired heat level.
• For added texture, sprinkle fried shallots or crushed peanuts on top before serving.
• If you prefer a more intense flavor, marinate the tempeh slices briefly in soy sauce and a touch of garlic before adding to the stir-fry.

Add-ons and Variations

• Incorporate sliced tofu or other vegetables such as bell peppers, carrots, or bean sprouts for variety.
• Add a splash of lime juice or tamarind paste at the end for a tangy twist.
• Top with a fried egg for a more filling vegetarian option.
• For a spicier kick, include more red chilies or a dash of chili oil.

Side Dishes

• Steamed jasmine rice or brown rice
• Indonesian fried shallots or crispy garlic chips
• Sambal oelek or chili sauce for extra heat
• Steamed vegetables or other stir-fried greens
• Grilled or fried chicken for non-vegetarian options

Improvements and Variations

• Experiment with different sauces such as kecap manis (sweet soy sauce) for a sweeter profile.
• Use fresh herbs like Thai basil or coriander for garnish.
• Adjust the spice paste ingredients by adding lemongrass or galangal for a more complex aroma.
• Incorporate shredded coconut or toasted sesame seeds for additional flavor and texture.

Save and Store

This dish is best enjoyed fresh but can be stored in an airtight container in the refrigerator for up to 1 day. Reheat gently in a skillet over medium heat, adding a splash of water or oil to revive the dish. Due to the fresh vegetable content, avoid freezing, as the kangkung may lose its texture upon thawing. To keep the tempeh crispy, consider adding it fresh during reheating rather than storing it together with the stir-fry.

FAQ

Can I use other leafy greens instead of kangkung?

Yes, spinach, bok choy, or Swiss chard can be substituted. Adjust cooking time accordingly, as different greens have varying tenderness and cooking requirements.

Is this dish suitable for vegans?

Absolutely, just replace the oyster sauce with a vegan alternative like mushroom sauce or soy sauce. Ensure all other ingredients are plant-based.

What is the best way to prepare tempeh for stir-frying?

Slice tempeh thinly and optionally marinate briefly in soy sauce or spices for enhanced flavor. Fry or bake before adding to the stir-fry for extra texture, but in this recipe, raw slices are sufficient as they absorb flavors during cooking.

How can I make this dish spicier?

Add more red chilies or include chili oil, sambal, or cayenne pepper during cooking to intensify the heat.

Can I make this dish gluten-free?

Yes, choose gluten-free oyster sauce or tamari and ensure all sauces used are labeled gluten-free. Verify ingredient labels to avoid cross-contamination.
