🛒 Ingredients

4 servings

4
  • 8 tablespoons water
  • 2 tablespoons granulated sugar
  • 2 tablespoons soy sauce
  • 2 tablespoons tomato paste
  • 4 tablespoons white vinegar
  • 1½ tablespoons cornstarch
  • 6 tablespoons cold water (to dissolve the cornstarch)

Directions

  1. 1

    Pour 8 tablespoons of water into a small saucepan and bring to a gentle simmer over medium heat.

  2. 2

    Add the sugar, soy sauce, and tomato paste, stirring continuously until the sugar is fully dissolved and the mixture is smooth.

  3. 3

    Pour in the white vinegar and stir well to combine.

  4. 4

    In a small bowl, whisk the cornstarch into the 6 tablespoons of cold water until lump-free, then slowly stream the slurry into the saucepan while stirring constantly.

  5. 5

    Cook over low heat for 2–3 minutes, stirring, until the sauce thickens to a glossy, coating consistency. Serve warm or at room temperature.

💡 Chef's Tip

Swap white vinegar for rice vinegar for a milder, more authentic Asian flavor. A few drops of sesame oil or a pinch of garlic powder stirred in at the end takes this sauce to the next level.
