Inspired by The Art of Living According to Joe Beef (Ten Speed) by Frédéric Morin, David McMillan and Meredith Ericsson I played around with Joe Beef’s version of homemade mustard, and came up with my own recipe, taking a nod from them by adding a dose of Canadian maple syrup to the batch. I added a spoonful of prepared horseradish to liven it up further. If you want to skip the wine, add water in its place. I’ve seen versions that used beer, too. Note that I used white (or yellow) mustard seeds. There are darker seeds are much stronger. I didn’t use them with this batch but it might be interesting to do a mix or use those instead. You can find mustard seeds in most supermarkets as well as Indian markets. The turmeric gives the mustard a lively color, doesn’t it? You could tone it down by adding less, although I find it rather amusing.
Combine all the ingredients, except the horseradish, in a stainless-steel bowl. Cover, and let stand for 2-3 days.
Put the ingredients in a blender and whiz until as smooth as possible. Add 2 to 4 tablespoons of water if the mustard is too thick. Blend in the horseradish, if using.
