The use of aromatics such as shallots, garlic, and fiery curly red chilies adds layers of depth, while seasonings like salt, seasoning powder, palm sugar, and sweet soy sauce contribute to a harmonious sweet-savory balance.

Instructions

Step 1: Preparing the vegetables

Start by carefully washing the green mustard greens. Fill a large bowl or basin with cold water and submerge the greens, gently swishing to remove dirt and grit. Rinse thoroughly at least 2-3 times until the water runs clear. Drain excess water using a colander. Once cleaned, trim the tough stems if desired, but typically, the tender parts of the greens are sufficient to use. Chop the greens into manageable bite-sized pieces—roughly 2-inch segments—making it easier to stir-fry and ensuring even cooking. Set aside in a clean bowl or on a plate.

Step 2: Preparing the tempeh

Remove the tempeh from its packaging, and if it is in a large block, cut it into small, uniform cubes approximately ½ inch in size. Uniform cubes ensure even cooking and a crisp exterior. To enhance flavor and texture, some cooks prefer to lightly steam or boil the tempeh for 5 minutes before stir-frying, which can reduce bitterness and improve digestibility, but this step is optional. After cutting, set the diced tempeh aside on a plate.

Step 3: Preparing aromatics and seasonings

Peel the shallots and garlic cloves. Use a sharp knife or a vegetable peeler to thinly slice the shallots into rings or strips. Mince or finely chop the garlic into small pieces to release maximum flavor during stir-frying. Rinse the curly red chilies, remove stems, and slice them into thin rounds or small strips, depending on spice preference. Chop the palm sugar into small pieces, making it easier to melt during cooking, or use a small grater to finely shred it.

Step 4: Heating the wok and stir-frying aromatics

Place a wok or large skillet on the stove over medium heat. Add a tablespoon of neutral oil—such as vegetable or canola oil—and allow it to heat until shimmering. Once hot, add the sliced shallots, garlic, and chilies. Stir continuously with a spatula or wooden spoon to prevent burning, cooking until the shallots turn translucent and fragrant, about 1-2 minutes. Add the chopped palm sugar and cook for another 30 seconds, allowing it to melt slightly and combine with the aromatics, creating a fragrant base for the dish.

Step 5: Cooking the tempeh

Add the diced tempeh into the wok, spreading it evenly. Stir-fry the tempeh over medium-high heat for 3-5 minutes, turning occasionally to achieve a golden-brown exterior. The goal is to develop a slight crispness on the outside while keeping the inside tender. If the pan becomes too dry, add a splash of water or additional oil to facilitate even browning. This process enhances the nutty flavor of the tempeh and adds texture to the dish.

Step 6: Seasoning the stir-fry

Sprinkle salt, seasoning powder, and an additional pinch of palm sugar if desired. Stir well to evenly coat the tempeh and aromatics with these seasonings. The seasoning powder can be a store-bought Indonesian seasoning mix or a homemade blend, but always adjust to taste. Continue stirring to distribute the flavors thoroughly, allowing the seasonings to meld with the ingredients.

Step 7: Creating a light sauce

Pour in a small amount of water—about 2-3 tablespoons—to create a light sauce base. Stir and scrape the bottom of the wok to lift any browned bits, which contribute flavor. This step helps to loosen any fond and ensures the seasonings and aromatics are well incorporated. Let the mixture simmer for about 1-2 minutes, allowing the water to reduce slightly and intensify the flavors.

Step 8: Adding the greens

Introduce the chopped green mustard greens into the wok. Toss or stir vigorously to combine with the aromatic and seasoned tempeh mixture. Cover the wok with a lid or keep it uncovered, depending on your preferred texture. Cook for approximately 2-3 minutes until the greens wilt but are still bright and slightly crunchy. The greens should retain their vibrant green color, and their slightly bitter taste will balance the sweetness and savory elements of the dish.

Step 9: Final seasoning and finishing touches

Pour in the sweet soy sauce (kecap manis), starting with 1 tablespoon. Stir thoroughly to evenly distribute the sauce, which adds a rich sweetness and glossy finish. Taste the dish and adjust seasonings as needed—adding more salt, sugar, or soy sauce based on your preference. The dish should have a balanced profile of sweet, savory, and slightly bitter flavors, with a hint of spice from the chilies.

Step 10: Serving the dish

Once the greens are tender yet still crisp, and the sauce has thickened slightly, remove the wok from heat. Serve immediately while hot, accompanied by steamed jasmine rice or any preferred rice variety. The combination of greens, crispy tempeh, and aromatic seasonings makes for a wholesome, flavorful meal that highlights Indonesian culinary traditions.

Preparation Tips

• Vegetable selection: Fresh, vibrant greens are essential for the best flavor and texture. If sawi ijo is unavailable, you can substitute with spinach, kale, or mustard greens from other cuisines.
• Tempeh prep: For a milder flavor, steaming tempeh briefly before stir-frying can reduce bitterness. Alternatively, marinate the tempeh in soy sauce, garlic, and a splash of lime for extra flavor.
• Spice level adjustment: Control the heat by varying the quantity of curly red chilies. For milder dishes, remove seeds or substitute with milder peppers.
• Seasoning alternatives: If Indonesian seasoning powder is unavailable, use a pinch of turmeric, coriander, or a dash of fish sauce (for non-vegans).
• Cooking technique: Maintain high heat during stir-frying to prevent sogginess and to develop flavor through quick browning.
