Whisk together all ingredients until a smooth sauce forms. Store in a covered container until using, or use immediately.
To add to a stir fry, use with a 4-serving stir fry like Tofu Stir Fry or Cauliflower Stir Fry. It also works with 1 pound protein like chicken, shrimp, or beef. Cook all the vegetables, then turn off the heat and add the sauce, stirring until it thickens.
