Prep time: 15 minutes
Total time: 25 minutes
3 cubes white fermented tofu (about 1/2 ounce|20 grams)
1 teaspoon Chinese black vinegar
1 teaspoon liao jiu or bai jiu
1 teaspoon light soy sauce
3/4 teaspoon granulated sugar, divided
2 tablespoons peanut oil
1 pound|450 grams kangkong (water spinach), cut crosswise into 2 to 3-inch pieces, rinsed and drained
1/4 teaspoon kosher salt
1 teaspoon peeled and minced ginger
4 thin slices red chili
1 small garlic clove, minced
1. In a small bowl, mash the tofu with chopsticks. Stir in the vinegar, liao jiu, soy sauce, and 1/4 teaspoon of sugar until it forms a slightly lumpy paste.
2. Heat a wok over high until it begins to smoke. Swirl in 1 tablespoon of oil. When it begins to smoke, add the kangkong and gently stir-fry it until wilted and soft, about 2 minutes. Transfer the greens to a plate and rinse the wok clean.
3. Return the wok to high heat until smoking. Swirl in the remaining oil, then add the ginger, chili, and garlic. Cook for 1 minute, or until fragrant. Pour in the fermented tofu mixture and, when it begins to boil, return the kangkong to the wok. Bring it to a gently simmer, stirring. Add in the remaining 1/2 teaspoon of sugar and season with salt. Transfer the greens to a platter to serve.
