What Exactly Is Mustard Water?

Mustard water isn’t just watered-down mustard—it’s a versatile byproduct or preparation involving mustard seeds, vinegar, and sometimes salt and spices, diluted with water. Depending on its origin and use, it can be a thin liquid extracted during mustard production or a DIY concoction used for culinary or household purposes.

Commercially, mustard water may refer to the run-off from industrial mustard paste production, which is sometimes repurposed as a cleaning agent or food additive. At home, however, mustard water typically refers to a simple mixture of mustard (usually yellow or Dijon) and water, sometimes with vinegar added for preservation or acidity balance.

Key Ingredients

• Mustard Seeds: Ground to release pungent compounds like allyl isothiocyanate.
• Vinegar: Balances heat and acts as a preservative.
• Salt: Enhances flavor and prolongs shelf life.
• Water: Dilutes the mixture to achieve desired consistency.
