No reviews

A powerful, 5-ingredient Chinese hot mustard sauce that delivers the classic sinus-clearing heat found in the best dim sum houses.

  • Total Time: 25 minutes
  • Yield: 1/2 cup 1x

Ingredients

Scale

1/2 cup dry mustard powder (Oriental style)
1/4 cup ice-cold water
1 teaspoon rice vinegar
1/2 teaspoon toasted sesame oil
1/4 teaspoon salt
1/2 teaspoon sugar (optional, to balance bitterness)

Instructions

Step 1: Sift the dry mustard powder into a small glass or ceramic bowl to remove any lumps, ensuring a smooth chinese hot mustard sauce texture.
Step 2: Gradually whisk in the ice-cold water, one tablespoon at a time, until the mixture forms a smooth, thick paste.
Step 3: Stir in the rice vinegar, toasted sesame oil, salt, and sugar until fully incorporated.
Step 4: Cover the bowl with plastic wrap and let the chinese hot mustard sauce sit (bloom) at room temperature for at least 20 minutes to develop its maximum heat.
Step 5: Give the sauce one final stir before serving. If it is too thick, add a few drops of water until the desired consistency is reached.

Notes

Always use cold water for the hottest result. The heat will naturally dissipate after 24 hours, so make it fresh for the best experience.
