Now that I’ve made this whole grain champagne Dijon, I will be trying to make all different flavors. Not to mention that a $2.69 bag of mustard seeds makes about $50 bucks worth of gourmet mustard. I used just brown seeds and you can find them at Indian markets or finer grocery stores. I made a big batch so I could give some away too. You will need a large mouth glass jar and your stick blender.
1 cup Champagne or dry sparkling
1 cup cider vinegar
1 cup whole brown mustard seeds
1 generous teaspoon of sea salt
Put everything in your jar and let sit in a dark corner for 3 days. Then blend with your stick blender for about 7-10 minutes. You want the seeds to be just flecks and the mixture to emulsify. You’ll never buy mustard again. Keep refrigerated for months, but it will lose some of its punch over time so enjoy right away.
