Does anyone know where I can pick up some violet mustard in Boston or Cambridge? I suppose I could attempt to make some myself, but this would be infinitely easier.
My guess is that Formaggio Kitchen would have it. They list a "Beaufor Violette Mustard (mout a raisin)" on their website, but maybe call ahead to see if they have it in stock?
making violet mustard isn't difficult but it is time consuming:
2 cups red wine
2 cups port
2 cups black grapes
boil slowly for approx 1 hour
add 4 ounces dry mustard (i use coleman's brand to avoid bitterness) smoothed in 1/4 to 1/2 cup cold water or wine vinegar [ or you can use 1 cup dijon mustard ]
and 1 cup whole grain (deli style) mustard
stir to incorporate ingredients well
put back on low heat to reduce (or use a double boiler) and stir until you get the right consistency
