A white porcelain bowl holds translucent gray-brown sweet-potato noodles in a glossy red hot-and-sour broth, with crushed peanuts, white sesame, cilantro, one baby bok choy and wooden chopsticks across the rim.

This is a simplified home version, not the traditional restaurant method.
Suanlafen is a street snack, and a bowl is quick to make at home: sweet-potato noodles, a sour-and-hot sauce, peanuts and greens. The amounts below are my own choices at home, drawn from two recipes. Cooking times for the noodles vary, so I judge by biting one to check for a hard core. This is a simplified home version: I do not make a pork-intestine broth and use ready-made chicken broth instead.
Ingredients
Dried sweet-potato noodles 100 g
Baby bok choy 2 heads
Cooked peanuts 30 g, crushed
Light soy sauce 2 tablespoons, about 30 ml
Black vinegar 3 tablespoons, about 45 ml
Chili oil 1 tablespoon, about 15 ml
White pepper a pinch
Garlic 1 clove, minced
Chicken broth about 200 ml, heated
White sesame seeds 1 teaspoon
Cilantro a little, chopped
Steps
Soak the noodles in cold water for about 1 hour, until soft.
If the peanuts are raw, toast them in a dry pan on low heat until cooked and fragrant, cool them and crush them.
In a large bowl, combine the soy sauce, 2 tablespoons of the vinegar, the chili oil, white pepper and garlic, pour in the hot chicken broth and stir.
Bring a pot of water to a boil and cook the noodles. I give them about 7 minutes and bite one, and they are done when there is no hard core; for the last half minute I add the bok choy.
Lift the noodles and greens into the bowl, sprinkle over the crushed peanuts, sesame seeds and cilantro, taste the broth, add the remaining vinegar if it is not sour enough, and eat while hot.
Tips
I find soaked noodles cook more evenly inside and out, which is my own experience.
I start with 2 of the 3 tablespoons of vinegar and add the rest after tasting; this is my own way.
