I have been making mustard at home for the last year or so, and find I like it better than any store bought mustard. I first learned about this off of Pintrest, and the results have been great from the beginning. Here is the link to the sustainable food site that has directions.. http://www.attainable-sustainable.net/homemade-grainy-mustard-yes-really/ I use red wine vinegar, turmeric, salt, and about a half tablespoon of brown mustard seeds for every cup of yellow mustard seed. That generally makes about 4-5 cups of finished mustard. Adding a little honey makes an amazing honey Dijon dressing. Best of all? No refrigeration. Because it's just the mustard, vinegar, turmeric, and salt, you do not need to can it or store it in the fridge. I just got out the last jar of mustard from last year, and it's even better than when I made it! The flavors have mellowed, and some of the "boldness" has settled out, leaving a delicious mustard that even the little kids love! And in a SHTF situation, having little comfort items like this can probably make the situation seem a little more bearable!
