Another addition to Mocktoberfest.
3 tablespoons yellow mustard seeds
2 1/2 tablespoons brown mustard seeds
1/3 cup Hefeweizen ale
1/3 cup white wine vinegar
1 shallot, minced (about 2 tablespoons)
Pinch ground allspice
3/4 teaspoon salt
1/4 teaspoon white pepper
In a non-reactive bowl, combine all ingredients and refrigerate overnight, covered.
Transfer the mustard mixture to a blender and process until mustard has obtained the desired texture and thickness; it is equally delicious whether you leave it chunky or smooth. Store in an airtight, non-reactive container in the refrigerator for up to 2 weeks.
