What each ingredient does

Mustard
Supplies the main pungent flavor and the thick, smooth body of the condiment.
Salt
Seasons the mixture and helps preserve it.
Horseradish vinegar
Adds sharp acidity and a sinus-clearing heat that cuts through the mustard.
Chili vinegar
Adds acidity and chili heat, balancing the mustard's sharpness.

The step that matters

Seal the jars tightly for storage. Air exposure lets the mixture oxidize and lose its sharp flavor over time. A tight seal keeps air out and helps the condiment stay fresh for longer.
