What each ingredient does
- Mustard flour
- Provides the pungent flavor and thick body that forms the paste when mixed with water.
The step that matters
Adding the water in two portions. Mustard flour releases its pungent compounds when it meets water, and the heat and strength of the flavor develop over several minutes. Adding water in stages lets you reach a smooth, lump-free paste before thinning it to the final consistency.
