This is my third or forth go at making whole grain mustard and its still a work in progress. I remember thinking to myself how simple it should be. Just throw some mustard seeds in the food processor with a little wine and vinegar and poof great mustard appears. Unfortunately its not that easy as I have found out. The process is simple the ratios are still in question but in the end it has to do with preference. The first step is seeds selection, yellow, brown, black, Chinese (Hot) or what I prefer a blend. Next you need to soak them which brings in more variables a la what liquid to use. Water is the classic soaking medium but you can use anything from vinegar, wine, beer, champagne, or your own custom mix. Referring to James Peterson's book Sauces he uses four ounces of seeds
to twelve ounces of liquid being red wine and red wine vinegar equal
parts. The next dilemma is how long to soak the seeds and I have no definite answer its all up to preference. Ive read anything from eight hours to three days but Ill go with James Peterson who says soak over night. At this point its time to decide if you want to add anything else to the soak i.e. shallots, garlic, herbs, or spices. Once your mixture has soaked overnight its time to blend so toss your mix in the food processor add in salt and pepper and if your using sugar or honey do so now. Also if you choose not to use vinegar in the soaking liquid now would be the time to add it. Process until desired consistency or thickness is reached. The mustard at this point will be hot as fire and maybe a bit bitter but these things will level out to an extent with time. Your mustard will be a great addition to aiolis, sauces, vinaigrette's, or straight up on a nice homemade sausage.
The recipe I used:
3 ounces Yellow Mustard Seeds
3 ounces Brown Mustard Seeds
12 ounces Shiner Bock
1 Shallot (diced)
2 Galric cloves (smashed)
2 Tablespoons Herbs de Provence (dried)
2 Tablespoons Brown Sugar
1 Tablespoon Kosher Salt
1 Teaspoon Black Pepper (fresh ground)
1 Teaspoon Turmeric
1/2 Cup Raw Apple Cider Vinegar
1/4 Cup White Wine
I think I would cut back or omit the sugar and use a distilled vinegar next go round to cut the sweetness and add a little more punch.
Note* I get all my seeds, dried herbs, and spices from Pendery's Spice Shop here in Fort Worth Texas.
