Salty Soy Milk Soup

Salty soy milk is a breakfast staple where unsweetened, hot soy milk is curdled slightly by acidic seasonings, then topped with savory elements like scallions, dried shrimp, and chili oil. It relies on the reaction between the heat of the milk and the vinegar to create a soft, custard-like texture immediately before eating.

Ingredients

  • 3 cups unsweetened soy milk
  • 1 tbsp chinkiang black vinegar
  • 1 tsp light soy sauce
  • 1 pinch salt
  • 1 tbsp dried shrimp, soaked and chopped
  • 1 tsp sichuan chili oil
  • 2 tbsp scallions, finely sliced
  • 1 piece youtiao (fried dough stick), sliced

Step by step

  1. Prep the bowls

    Divide the vinegar, soy sauce, salt, and dried shrimp between the two bowls.

  2. Heat the milk

    Bring the soy milk to a low simmer in the saucepan. Watch the surface closely; remove from heat the moment you see small bubbles forming at the edges.

  3. Combine

    Pour the hot milk quickly into the center of the bowls. Do not stir.

  4. Garnish

    Top with sliced youtiao, scallions, and a drizzle of chili oil. Serve immediately while it is still steaming.

Questions people ask

Can I use store-bought refrigerated soy milk?

Yes, but ensure it is unsweetened. Sweetened milk will produce a cloying, off-putting result when mixed with vinegar and soy sauce.

Why did my milk not thicken?

The milk was likely not hot enough. It needs to be near 180°F (82°C) to effectively react with the acid.

Tips

  • If the milk forms a skin on top while heating, skim it off before pouring so the texture remains smooth.
  • If you cannot find black vinegar, a high-quality rice vinegar works, though it lacks the depth of the malt-based version.
  • The reaction happens once. Stirring the bowl after the initial pour will break the delicate curds and make the milk watery.

Variations

  • Pickled Mustard Green: Add one tablespoon of finely diced pickled mustard greens (zha cai) to the bowl for a sharp, crunchy bite.
  • Nutty Finish: Add a teaspoon of toasted sesame oil or crushed peanuts for an earthier flavor profile.
