Mustard Powder

The dried and ground version of yellow mustard seed, mustard powder gets mixed with vinegar or water to make classic yellow mustard. (You can thank an inventor at the 1904 St. Louis World’s Fair for creating the stuff we slather on hot dogs.) But to only think of it as a condiment is short-sighted. This finely milled powder goes great with cheese sauces and slow-cooked meat dishes.
