Step‑by‑Step Instructions for Spicy Hot and Sour Noodle Soup
Step 1: Prepare Meat Toppings
In a skillet, heat 2 tablespoons of peanut oil over medium heat until shimmering. Add ½ pound of ground pork and cook for about 4–5 minutes, stirring frequently, until browned. Pour in 2 tablespoons of Shaoxing wine and 1 tablespoon of dark soy sauce, mixing well for an additional 2 minutes. Once the pork is well combined with the sauce, remove it from heat and set aside.
Step 2: Make the Broth
In four small bowls, evenly distribute ¼ cup of sliced green onions, 2 minced garlic cloves, 2 tablespoons of homemade chili oil, 2 tablespoons of Chinkiang vinegar, 1 tablespoon of light soy sauce, and 1 teaspoon of sugar. If desired, add ½ teaspoon of ground Sichuan peppercorns for an extra kick. Bring 4 cups of chicken broth to a boil in a separate pot and pour it hot over the prepared ingredients in the bowls, filling them to the brim.
Step 3: Prepare Noodles
While the broth is boiling, bring a large pot of water to a rolling boil. Add 8 ounces of fresh sweet potato noodles and cook according to package instructions, about 3–5 minutes, until al dente. Once cooked, drain the noodles in a colander and rinse them under cold water to stop the cooking process. This ensures their perfect chewy texture in your Spicy Hot and Sour Noodle Soup.
Step 4: Assemble the Soup
After preparing the broth, divide the rinsed noodles equally among the bowls filled with the hot broth. Top each bowl with cooked ground pork, a sprinkle of roasted peanuts for crunch, a handful of chopped cilantro or extra green onions for freshness, and a squeeze of any additional chili oil, if desired. Serve each bowl immediately while steaming hot to enjoy the full flavors of this comforting dish.
