What each ingredient does

Horse-radish
Supplies the sharp, pungent heat that defines the condiment.
Mustard powder
Adds sharp, pungent flavour and body that helps the mixture set into a paste.

The step that matters

Adding water gradually. Mustard powder develops its pungency when it meets liquid, and its consistency changes quickly. Adding water in small amounts lets you stop at a smooth paste before it becomes too thin.
