There are over 40 different varieties of mustard plants, but three are the most popular for culinary use; black, brown, and white mustard seeds typically go into recipes and making mustard. All three varieties are found in the U.S. as well as other parts of the world.
Mustard is the second most-used spice in the United States, as its usage is only exceeded by the peppercorn. And it’s no wonder since mustard works well with all types of meats, pork, poultry, and seafood. You may be used to standard yellow prepared mustard, but there are other wonderful varieties of seeds and prepared mustards to experiment with.
