Fish ball soup (yu wan tang)

Freshly pounded fish balls bound with sweet potato starch, poached in a clear broth flavored with pickled Chinese mustard greens, ginger, and rice vinegar.

Ingredients

  • 500 g Fresh white fish fillet (cod, hake, or sea bass)
  • 100 g Sweet potato starch
  • 80 g Pickled Chinese mustard greens (suan cai)
  • 1 piece Fresh ginger
  • 2 pieces Scallion
  • 1 bunch Fresh cilantro
  • 1 piece Egg white
  • to taste Rice vinegar
  • to taste Ground white pepper
  • to taste Salt
  • 1 l Water

Method

  1. Finely grate the ginger and thinly slice the scallion into rings; chop the pickled mustard greens after rinsing them if they are too salty.
  2. Scrape the flesh from the fish fillet with a spoon, avoiding the bones, then roughly chop without pureeing it too finely to retain the stringy texture typical of Wenzhou.
  3. In a cold bowl, mix the fish with the egg white, salt, and white pepper; knead by lifting the mixture until it becomes sticky and elastic to the touch.
  4. Gradually incorporate the sweet potato starch while continuing to knead until the paste is smooth, slightly elastic, and no longer sticks to your fingers.
  5. Bring the water to a simmer with the grated ginger and a portion of the pickled mustard greens; maintain a clear broth without a rolling boil.
  6. Form irregular balls by scooping the paste with a spoon or pressing it between your thumb and index finger, then gently drop them into the simmering broth.
  7. Poach until the balls float to the surface, a sign that they are cooked and the texture is perfectly elastic.
  8. Add the remaining pickled mustard greens, rice vinegar, and white pepper; adjust the seasoning to taste.
  9. Serve immediately in warm bowls, sprinkled with sliced scallion and fresh cilantro.
