Around the year 530 B.C., Pythagorus advocated mustard powder as an antidote for scorpion bites. Today ground mustard lends recipes a piquant zing with its uniquely sharp heat shared only with horseradish and wasabi. Mustard powder can be combined with vinegar, salt, and a pinch of sugar to create a condiment of prepared mustard. The ground seeds make an excellent emulsifier for salad dressing and gravies as well. Mustard's spicy nose-clearing kick cuts deliciously through the richness of oily dressing and fatty gravies.
