Finding the right balance of four simple ingredients, paired with a little time, is all that's needed to make an excellent whole grain Dijon mustard at home.
- 1/4 cup brown mustard seeds
- 1/4 cup yellow mustard seeds
- 1/2 cup dry white wine
- 1/2 cup white wine vinegar
- 1/2 teaspoon Kosher salt
- 1 teaspoon light brown sugar (optional)
Place mustard seeds, wine, and vinegar in a small bowl or container, cover, and let soak at room temperature for two days.
Transfer mustard seeds and liquid to jar of a blender. Add in salt and sugar, if using, and puree until mustard paste forms, but whole seeds still remain. Transfer to an airtight container and let rest in refrigerator for 2 days before use.
