Mustard is an ancient and versatile condiment. Originally meaning hot or burning must from the Latin mustum ardens, the seeds of the Sinapis hirta (white or yellow mustard plant) were likely first used as a condiment by the ancient Romans. Nowadays, most of us just pick the stuff up in the grocery store, but the process of making mustard is rather simple, and when you make it yourself, you have a lot of options.
Practically any variety of liquids can be used to make an acidic bath for Indian (Brassica juncea), black (B. nigra), or white/yellow seeds to soak in. Once they're hydrated and soft, all that's left to do is grind the mustard to your desired consistency. Think you can do this? You're right.
