China Moon House Mustard Sauce

An invariable disappointment to those who expect the standard Chinese restaurant mustard sauce—an acrid blend of dry mustard and water—this is a silky sauce lush with the flavors of dark sesame oil and Dijon mustard. It will keep forever in the refrigerator.


  • ½ cup unflavored Dijon mustard
  • ¼ cup Japanese sesame oil
  • 3 tablespoons unseasoned Japanese rice vinegar
  • ¼ teaspoon sugar
  • pinch of fine sea salt


Whisk all of the ingredients together until well blended. Store, refrigerated, in an impeccably clean glass jar. If the sauce separates, simply whisk it to emulsify.
