Mince 2 cloves of garlic, chop chilis, green onions and cilantro. Set aside
Follow the instructions on the package to make the sweet potato noodles. Once they’re done, remove from water and rinse in cold water. Let it rest in a colander
In a pot, heat 600 ml of broth until it comes to a boil. Once it boils, put the cooked sweet potato noodles in and let it come to a boil again. Turn off heat
Put half the noodles and half the soup into each bowl (for 2 servings)
In a small pot, turn heat on to medium-high, add 2 tsp oil and half the garlic, chilis and green onions. Fry until aromatic
Add 2 tsp light soy sauce, ½ tsp dark soy sauce, 1 tbsp oyster sauce, 1 tsp sugar and 1 tsp Guilin chili sauce to the pot. Mix well. Turn off heat. Add 2 tbsp Chinkiang vinegar
Use a spoon to spoon the vinegar sauce into each bowl of noodles. Mix well
Taste test and make adjustments. If it’s too spicy, add some hot water and add more seasonings. Since the chili sauces, soy sauces and broth may contain varying amounts of salt, you can decide if any salt or more soy sauce is needed
Once you’re happy with the taste, add 2 tbsp peanuts, 2 tbsp spicy pickled bamboo shoots and 2 tbsp pickled mustard greens.
Add the rest of the garlic, chilis and green onions. Top with cilantro
Serve
