Instructions

  1. Step 1: Bring a pot of water to boil and blanch 200 g peeled and 1/4-inch thick sliced lotus root for 2 minutes until just tender but still crisp; drain and set aside.
  2. Step 2: Heat 3 tbsp vegetable oil in a wok over medium-high heat. Add 3 minced garlic cloves, 1 tbsp minced ginger, and 1 tbsp rinsed, chopped fermented black beans, stir-frying for 30 seconds until fragrant.
  3. Step 3: Add the blanched lotus root slices and 1 medium each of sliced red and green bell peppers, stir-frying vigorously for 3 minutes until vegetables are bright and slightly softened.
  4. Step 4: Add 1 1/2 tbsp soy sauce, 1 tsp sugar, and 50 ml water, tossing everything together and cooking for another 2 minutes until the sauce thickens slightly and coats the vegetables.
  5. Step 5: Finish by drizzling 1 tsp sesame oil and folding in 1 chopped spring onion stalk before removing from heat and serving immediately.
