Return the wok to medium heat, add cooking oil, Pixian spicy broad bean paste, and chili powder. Stir-fry until fragrant. Pour in chicken broth. Add tofu, minced beef, 1 tbsp/10 g fermented soybean, and ½ tbsp/8 ml soy sauce. Turn heat to high, bring to a boil, then lower the heat to medium and cook for 3-5 minutes. Then add leek slices and slurry to thicken the sauce until it clings glossily to the meat and tofu.
