Step‑by‑Step Instructions for Hot and Sour Noodle Soup
Step 1: Prepare the Meat Toppings
In a large skillet over medium heat, warm 2 tablespoons of peanut oil until shimmering. Add 100g of ground pork and sauté for 4-5 minutes until browned. Once cooked, pour in 1 tablespoon of Shaoxing wine and 2 tablespoons of dark soy sauce, stirring well to combine the flavors. Cook for an additional minute, then remove from heat and set aside.
Step 2: Make the Broth
In a pot, bring 4 cups of chicken broth to a rolling boil over high heat. As the broth heats, gather the remaining ingredients for the broth in separate bowls: 2 tablespoons of Chinkiang vinegar, 1 tablespoon of sugar, and a sprinkle of ground Sichuan peppercorns if using. Once the broth is boiling, carefully stir in these ingredients to enhance the depth of flavor.
Step 3: Prepare the Noodles
While the broth is simmering, cook 200g of sweet potato noodles according to the package instructions, typically about 3-5 minutes until al dente. After cooking, drain the noodles in a colander and rinse them under cold water to stop further cooking and prevent them from sticking together. This step ensures a delightful chewy texture in your Hot and Sour Noodle Soup.
Step 4: Assemble the Bowls
Divide the cooked noodles among serving bowls, ensuring they are nestled nicely at the bottom. Carefully ladle the hot broth over the noodles, filling each bowl generously. Then, layer the sautéed ground pork on top of the noodles, followed by your choice of toppings such as roasted peanuts or fried soybeans for added crunch.
Step 5: Serve Hot
Finish your hearty Hot and Sour Noodle Soup by garnishing with chopped cilantro and green onions if desired. Serve immediately while the broth is steaming hot and aromatic. Encourage everyone to adjust the spice levels by adding homemade chili oil to taste, delivering a warming experience with every spoonful.

Make Ahead Options
Suan La Fen is an ideal recipe for meal prep, allowing you to savor its delightful flavors without a last-minute rush. You can prepare the soup base up to 3 days in advance by cooking the broth and sautéing the ground pork, then refrigerating them separately to maintain their quality. Store them in airtight containers to prevent any absorption of odors. When you’re ready to enjoy your Hot and Sour Noodle Soup, simply reheat the broth and meat in a pot while cooking fresh noodles for a delightful texture. This way, you’ll have a soul-warming meal ready in no time, just as delicious as when freshly made!

Absolutely! This recipe can easily be made vegetarian or vegan by omitting the ground pork and using vegetable broth instead of chicken broth.
