Hot Chinese Mustard Sauce
Chinese mustard is fiery hot, so I moderate its power by creating a simple sauce which can be used in all sorts of ways. My favorite is with Wolfgang's Spring Rolls.
2 tablespoons Chinese dry mustard (or Colman’s English Mustard Powder)
2 teaspoons water
2 tablespoons rice wine vinegar
1/4 cup pickled ginger liquid
Juice of 1 lemon
Pinch of turmeric
1 tablespoon sugar
1 tablespoon chili oil
1 tablespoon Asian sesame oil
1 cup peanut oil
In a bowl, combine all the ingredients except the peanut oil. Stir until well blended. Slowly whisk in the peanut oil until emulsified. Set aside until needed. This can be prepared up to 1 week ahead.
