Oriental hot mustard is made with dry mustard – mustard that has been dried sufficiently so that when crushed it forms a powder. Oriental hot mustard powder which, like Dijon, is made with the stronger brown mustard seeds, called Brassica juncea. How do you transform mustard powder into hot mustard? If you prefer a hot, pungent mustard, all you need to do is add cold water, mix, and wait about fifteen minutes for the reaction to fully develop. The only thing to remember is that after the mustard reaches its peak strength at that point, it slowly begins to decline. If you’re not using it immediately, adding an acid such as vinegar or rice wine will stop the reaction and prevent the mustard from losing its sharp edge.
