## Step-by-Step Instructions
Here’s a detailed guide on how to cook delicious stir-fried kang kong:
**Step 1: Prepare the Kang Kong**
This is the most important step, as proper preparation ensures even cooking and prevents a tough, stringy texture.
1. **Wash Thoroughly:** Rinse the kang kong thoroughly under cold running water to remove any dirt or debris. Pay close attention to the stems, as they tend to trap more dirt.
2. **Trim the Ends:** Cut off the tough ends of the stems, about 1-2 inches from the bottom. These ends are often fibrous and less palatable.
3. **Separate Leaves and Stems:** Separate the leaves from the stems. The stems take longer to cook than the leaves, so it’s important to cook them separately.
4. **Cut Stems into Sections:** Cut the stems into 2-inch sections. You can also split thicker stems lengthwise to ensure they cook evenly.
5. **Keep Leaves Whole or Roughly Chop:** You can leave the leaves whole or roughly chop them into smaller pieces, depending on your preference. Chopping the leaves makes them easier to eat.
6. **Drain Well:** Drain the prepared kang kong well to remove excess water. This will prevent the stir-fry from becoming soggy.
**Step 2: Prepare the Aromatics**
While preparing the kang kong, also prepare the garlic and chilies.
1. **Mince Garlic:** Mince the garlic cloves finely. Mincing releases the garlic’s flavor and aroma more effectively than chopping.
2. **Slice Chilies:** Thinly slice the red chilies. Remove the seeds if you prefer a milder flavor. Remember to wash your hands thoroughly after handling chilies.
**Step 3: Stir-Fry the Kang Kong**
The key to a good stir-fry is high heat and quick cooking. This ensures that the vegetables remain crisp-tender and retain their vibrant color.
1. **Heat the Oil:** Heat the cooking oil in a wok or large skillet over high heat. The oil should be shimmering hot before you add the garlic and chilies.
2. **Sauté Garlic and Chilies:** Add the minced garlic and sliced chilies to the hot oil. Sauté for about 15-20 seconds, or until fragrant. Be careful not to burn the garlic, as it can become bitter.
3. **Add the Stems:** Add the kang kong stems to the wok and stir-fry for 1-2 minutes, or until they start to soften slightly. Keep the vegetables moving to prevent them from burning.
4. **Add the Leaves:** Add the kang kong leaves to the wok and stir-fry for another 1-2 minutes, or until they wilt and turn bright green. Avoid overcooking the leaves, as they can become mushy.
5. **Add Seasonings:** Add the soy sauce, oyster sauce (if using), sesame oil (if using), salt, pepper, and sugar (if using) to the wok. Stir-fry for a few seconds to combine the seasonings and ensure that the kang kong is evenly coated.
6. **Adjust Seasoning:** Taste and adjust the seasoning as needed. You may want to add more soy sauce for saltiness, chili for spiciness, or sugar to balance the flavors.
7. **Serve Immediately:** Serve the stir-fried kang kong immediately while it’s still hot and crisp-tender. It’s best enjoyed as a side dish with rice or noodles.
## Tips for Perfect Stir-Fried Kang Kong
* **Use High Heat:** High heat is essential for a good stir-fry. It allows the vegetables to cook quickly and evenly without becoming soggy.
* **Don’t Overcrowd the Wok:** Cook the kang kong in batches if necessary to avoid overcrowding the wok. Overcrowding can lower the temperature and result in steamed vegetables instead of stir-fried vegetables.
* **Prepare Ingredients in Advance:** Having all your ingredients prepped and ready to go before you start cooking will make the stir-frying process much smoother and more efficient.
* **Use Fresh Ingredients:** Fresh kang kong will have the best flavor and texture. Look for leaves that are vibrant green and stems that are firm and crisp.
* **Adjust Spice Level:** Adjust the amount of chili to your spice preference. You can also use chili flakes or chili paste instead of fresh chilies.
* **Don’t Overcook:** Overcooking the kang kong will result in mushy leaves and tough stems. Cook it just until the leaves wilt and the stems are slightly softened.
* **Wok Hei:** “Wok hei” is the elusive smoky flavor that’s characteristic of authentic stir-fries. To achieve wok hei at home, make sure your wok is very hot and your ingredients are dry. Using a carbon steel wok is also helpful.
## Variations and Additions

* **Top with Fried Shallots:** Sprinkle fried shallots over the stir-fry for added texture and flavor.
* **Spicy Sambal Kang Kong:** Incorporate sambal oelek or other chili pastes for a more intense spicy flavor.
* **Belacan Kang Kong:** Use belacan (shrimp paste) for a pungent and savory flavor. Be mindful of the strong aroma!
