Ingredients

Instructions

Step 1: Prepare the Ingredients

Begin by thoroughly washing the water spinach to remove any dirt or pesticides. Trim off the tough ends of the stems if necessary, and cut the greens into manageable lengths—about 4-6 inches—so they cook evenly and fit comfortably in your wok. Set aside in a clean bowl or on a cutting board.

Next, prepare the tempeh by slicing it into small, uniform cubes approximately 1/2-inch in size. Consistency in size ensures even cooking and a crispy exterior. For optimal texture, some prefer to lightly steam or boil tempeh for 2-3 minutes before stir-frying to remove any bitterness, but this is optional based on personal preference.

Crush and thinly slice the garlic cloves; slicing garlic enhances flavor release during stir-frying. Thinly slice the onion into small strips—this helps it cook quickly and evenly. Slice the red chilies into thin rounds, adjusting the quantity based on your spice tolerance. For extra heat, include the bird’s eye chilies, which are notably spicier and are traditional in Indonesian spicy dishes.

Step 2: Sauté the Aromatics

Heat a generous amount of cooking oil—about 2-3 tablespoons—in a large wok or a deep skillet over medium heat. Ensure the oil is evenly heated before adding aromatics to avoid burning.

Add the sliced garlic to the hot oil, and sauté for approximately 30 seconds to 1 minute until fragrant and lightly golden. Be careful not to let it burn, as burnt garlic imparts a bitter flavor.

Next, add the sliced onions and cook, stirring frequently, until they become translucent—about 1-2 minutes. Then, toss in the sliced red chilies and bird’s eye chilies if using. Stir-fry everything together for another 1-2 minutes, allowing the spices to release their aroma and flavor into the oil. This step forms the flavor base for the dish.

Step 3: Incorporate the Tempeh

Add the cubed tempeh to the wok, stirring to coat the pieces evenly with the aromatic oil and spices. Cook for about 3-4 minutes, stirring occasionally, until the tempeh begins to develop a light golden-brown exterior. The goal is to achieve a slight crispness on the outside while keeping the inside firm and tender.

If you prefer a softer tempeh, cook for a slightly shorter period; for crunchier tempeh, extend the cooking time slightly. For an even crispier texture, some cooks pan-fry tempeh separately until golden and then add to the stir-fry.

Step 4: Add Water Spinach and Seasonings

Once the tempeh is cooked to your desired crispness, add the water spinach to the wok. It will seem abundant at first but will wilt rapidly. Use tongs or a spatula to toss the greens with the tempeh, ensuring they are coated with the flavors.

Pour in a tablespoon or two of oyster sauce—adjust based on taste and dietary preference—and sprinkle in the Masako seasoning or salt. Stir well to combine, allowing the flavors to meld. The oyster sauce adds a savory, umami note and a subtle sweetness that balances the heat and earthiness.

Continue stir-frying for another 1-2 minutes, just enough to wilt the greens while maintaining their vibrant color and crunch. The greens should be tender yet crisp, not overcooked to mush.

Step 5: Final Adjustments and Serving

Taste the dish and adjust seasoning if necessary—adding more salt, oyster sauce, or chili for extra spice. The dish should have a good balance of heat, saltiness, and umami.

Serve the Tumis Kangkung Tempe Pedas hot, paired with steamed jasmine rice or your preferred grain. This dish is best enjoyed immediately to appreciate the contrasting textures of crispy tempeh and fresh greens.

Preparation Tips

• Use fresh water spinach for the best flavor and texture; older greens may be tougher and less vibrant.
• Slice chilies thinly to maximize heat transfer and flavor distribution throughout the dish.
• Adjust spice levels based on your preference; start small and add more if desired.
• For a vegan version, replace oyster sauce with a mushroom-based soy sauce or omit entirely.
• Ensure high heat during stir-frying to quickly sear the tempeh and retain the green’s freshness.
• Use a wide wok to give ample space for tossing ingredients and achieving even cooking.

Nutritional Information (per serving)

Tips and Tricks

• Prep all ingredients beforehand to facilitate quick cooking, especially since stir-fry dishes cook rapidly.
• Maintain high heat to achieve the characteristic slight charring and crispness of tempeh.
• For a smoky flavor, add a touch of smoked paprika or char the tempeh slightly in a dry pan before stir-frying.
• Use fresh, vibrant water spinach; avoid wilted or yellowing greens for optimal flavor and appearance.
• Experiment with different chili varieties to customize heat levels—preferably Thai bird’s eye for authentic spice.
• To enhance flavor complexity, add a splash of lime juice or a dash of fish sauce (if non-vegetarian).

Add-ons

• Fried shallots or garlic chips for added crunch and aroma.
• Chopped peanuts or cashews sprinkled on top for texture.
• Additional vegetables like sliced bell peppers, carrots, or bean sprouts for variation.
• Fresh herbs such as cilantro or Thai basil for garnish.

Side Dishes

• Steamed jasmine rice or brown rice
• Indonesian sambal or chili paste for extra heat
• Fried or boiled eggs for added protein
• Pickled vegetables or acar for a tangy contrast

Improvements and Variations

• Add a splash of coconut milk during stir-frying for a creamy, richer flavor profile.
• Incorporate sliced mushrooms or tofu for additional umami and protein.
• Opt for different greens like spinach or bok choy if water spinach is unavailable.
• Adjust spice levels by varying the number and type of chilies used.
• Experiment with different seasonings, such as kecap manis (sweet soy sauce) for a sweeter variation.

Save and Store

This dish is best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 1 day. To reheat, gently sauté in a pan over medium heat or microwave until warmed through. Keep in mind that greens may lose their crispness upon storage, and tempeh may absorb moisture, softening slightly.

FAQ

Can I make this dish vegan?

Yes. Simply omit oyster sauce or replace it with a vegan mushroom or soy-based sauce. Ensure that seasonings like Masako are vegan-friendly or substitute with sea salt.

What if I don’t have water spinach?

You can substitute with spinach, bok choy, or other leafy greens such as Swiss chard. Adjust cooking time accordingly to avoid overcooking.

How spicy is this dish?

The dish can be adjusted to your preferred spice level by adding more or fewer chilies. Bird’s eye chilies are quite hot, so use with caution if you are sensitive to spice.

Can I prepare the ingredients in advance?

Yes. Slice and wash all vegetables and proteins beforehand. Keep tempeh refrigerated and chilies in a sealed container until ready to cook. However, cook the dish just before serving for optimal freshness.
