Ingredients

Instructions

Step 1: Preparing the Ingredients

Begin by thoroughly washing the water spinach to remove any dirt or impurities. Hold the bunches under cold running water and gently agitate to ensure all grit is washed away. Once clean, separate the leaves from the stems. The stems are slightly tougher and thicker, so you may choose to cut them into smaller, bite-sized pieces, or leave them as they are if you prefer a more rustic texture. The leaves are tender and will wilt quickly during stir-frying. Set both aside in separate bowls or on a clean tray.

Next, prepare the tempeh. Cut the small block into small cubes or crumble it if you prefer a finer, more integrated texture with the sauce. The cubes should be roughly 1/2-inch in size for easy stir-frying. Crumbling tempeh will allow it to absorb flavors more thoroughly. Slice the shallots thinly, which helps them cook quickly and release their aromatic oils. Mince the garlic finely to maximize flavor release. Slice the tomato into wedges or small chunks. Thinly slice the large chili—adjust the amount based on your spice tolerance. Remember, the chili adds both heat and flavor, so you can add more or less depending on your preference.

Step 2: Heating the Wok and Sautéing Aromatics

Place your wok or large frying pan on medium heat and add the cooking oil. Allow the oil to heat until shimmering but not smoking, which ensures a proper stir-fry environment. Once hot, add the sliced shallots. Stir continuously using a spatula or stir-fry turner to prevent burning and to allow even cooking. Cook the shallots for about 2-3 minutes until they become fragrant and translucent. Then, add the minced garlic and continue to sauté for another 30 seconds to 1 minute. The garlic should become fragrant and slightly golden, but be cautious not to burn it, as burnt garlic imparts a bitter taste.

Step 3: Incorporating the Shrimp Paste and Chili

If you are using shrimp paste (terasi), add it now. Break it apart with your spatula and stir it into the aromatic mixture. The shrimp paste will dissolve quickly, releasing a rich, umami scent that characterizes many Indonesian dishes. Stir thoroughly to ensure even distribution. Be aware that shrimp paste can be quite pungent, so adjust the quantity to your taste and dietary needs.

Add the sliced large chili at this stage. Stir-fry for about 30 seconds to 1 minute, allowing the heat to infuse into the oil and aromatics. This step enhances the overall flavor profile and provides the signature heat of the dish. If you prefer milder flavors, you can reduce the chili slices or omit them altogether.

Step 4: Cooking the Tempeh

Next, add the prepared tempeh. If crumbled, sprinkle it evenly over the aromatic mixture, stirring to combine. If cubed, gently toss the cubes into the pan, ensuring they are coated with the flavorful oil and aromatics. Cook for about 3-4 minutes, allowing the tempeh to absorb the flavors and develop a slightly golden exterior. This step is essential to give the tempeh a nutty, savory taste and a firm texture that contrasts beautifully with the tender water spinach.

Pour in a small amount of water—about 1/4 cup—to help cook the tempeh thoroughly and create a light sauce. Stir well, scraping any browned bits from the pan’s bottom to incorporate more flavor. Let this simmer for 3-4 minutes until the water reduces slightly and the tempeh is tender and well-flavored.

Step 5: Adding Water Spinach and Tomato

Now, introduce the water spinach to the wok. Since water spinach wilts quickly, add the stems first, stirring to coat them with the sauce. After a minute, add the leaves and tomato slices. Continue stir-frying for another 2-3 minutes until the leaves are wilted and the tomatoes are slightly softened. The water spinach should be tender but still vibrant green, with a slight crunch in the stems if not overcooked. The tomatoes will release their juices, adding to the overall flavor and moisture of the dish.

Step 6: Seasoning and Final Adjustments

Assess the dish’s flavor balance at this point. Add salt and sugar gradually—start with a pinch of salt and about 1 teaspoon of sugar—and stir well. The salt enhances the umami, while the sugar balances the bitterness of the water spinach and the heat of the chili. Taste and adjust seasonings accordingly. For more heat, add additional chili slices or a dash of chili powder. For extra sweetness, sprinkle in a little more sugar. Continue cooking for another minute to allow flavors to meld.

Step 7: Serving

Once the water spinach is tender and the tempeh has fully absorbed the flavors, remove the pan from heat. Serve immediately, ideally over steamed jasmine rice or sticky rice, to complement the savory, aromatic qualities of the stir-fry. Garnish with additional sliced chili or fresh herbs if desired, and enjoy the authentic taste of Indonesian comfort food.

Preparation Tips

• Use fresh ingredients: Fresh water spinach, garlic, shallots, and tempeh yield the best flavor and texture. Avoid wilted or old produce.
• Adjust spice levels: The amount of chili can be tailored to your spice tolerance. For milder versions, reduce or omit the chili slices, or substitute with milder peppers.
• Control heat: Stir-frying requires high heat; ensure your wok is hot enough to sear ingredients quickly without burning.
• Batch cooking: If preparing larger quantities, cook ingredients in batches to maintain proper stir-fry technique and avoid overcrowding.
• Flavor enhancement: For a richer umami taste, consider adding a splash of soy sauce or fish sauce, but adjust salt accordingly.

Nutritional Information

Tips and Tricks

• Use a high-smoke-point oil: Peanut oil or vegetable oil works best for stir-frying to prevent burning and achieve high heat.
• Pre-cut ingredients: Prepare all ingredients before cooking to streamline the process and maintain high temperature during stir-frying.
• Don’t overcook the water spinach: Wilt it just enough to retain its nutrients and vibrant color. Overcooking results in loss of texture and flavor.
• Balance flavors: Taste as you go and adjust seasoning gradually to prevent over-salting or oversweetening.
• Customize spice level: Add more chili or spice powders if you prefer a fiery dish, or keep it mild for gentler palates.

Add-ons

• Fried shallots or garlic chips for extra crunch and flavor
• Chopped fresh herbs like cilantro or Thai basil for a fragrant finish
• Additional protein such as fried tofu or scrambled eggs for a heartier meal
• A squeeze of lime or calamansi for a citrusy brightness

Side Dishes

• Steamed jasmine or basmati rice
• Indonesian sambal or chili sauce for added heat
• Fried or grilled shrimp skewers
• Pickled vegetables or acar to add acidity and balance

Improvements

• Incorporate fermented condiments like kecap manis (sweet soy sauce) for a sweeter, richer flavor
• Add a dash of coconut milk during the stir-fry to create a creamy, tropical variation
• Use smoked or roasted chili powders for a deeper smoky flavor
• Experiment with different greens like bok choy or spinach for variety

Save and Store

This dish is best enjoyed fresh immediately after cooking. However, leftovers can be stored in an airtight container in the refrigerator for up to 1 day. Reheat gently in a pan or microwave, adding a splash of water or oil to revive moisture. Do not freeze, as water spinach’s delicate texture deteriorates upon freezing.

FAQ

Can I omit the shrimp paste?

Absolutely. Shrimp paste adds umami and depth but can be omitted for a vegetarian or vegan version. Consider adding a splash of soy sauce or mushroom sauce to compensate for the umami flavor.

Is water spinach available in regular supermarkets?

It may be less common in Western supermarkets but can often be found in Asian grocery stores. Look for fresh, vibrant bunches with firm stems and bright green leaves.

How spicy is this dish?

The heat level depends on the amount and type of chili used. Adjust according to your preference, starting with a small amount and increasing gradually.
