Mustard & Tarragon
The dried and powdered version of yellow mustard seed, ground yellow mustard 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. The finely milled powder goes great with cheese sauces and slow-cooked meat dishes.
