What each ingredient does
- Dry mustard
- Provides the pungent heat and bitter flavour that defines the condiment.
- Boiling water
- Hydrates the mustard powder, releasing its heat compounds into a smooth paste.
- Strong vinegar
- Adds acidity and thins the paste, and its sharpness helps balance the mustard's heat.
The step that matters
Gradually add boiling water to make a thick paste, stirring until smooth. Mustard's heat comes from enzymes and compounds that form when powder meets water. Adding the water slowly and stirring keeps the paste lump-free, and letting it rest briefly before adding vinegar lets the heat develop. Vinegar added too early can stop that development and leave the mustard mild.
