Homemade Whole Grain Mustard Recipe
- Quick Glance
- 10 M
- 2 D
- Makes about 2 cups
- 3/4 cup (177 ml) cider vinegar
- 1/2 cup (118 ml) cold water
- 1/3 cup (60 grams) yellow mustard seeds
- 1/3 cup (60 grams) brown mustard seeds
- 1 to 2 tablespoons (27 grams) packed light brown sugar
- 1 1/4 teaspoons salt
- 1. Combine the vinegar, water, yellow mustard seeds, and brown mustard seeds in medium bowl. Cover with plastic wrap and let stand at room temperature for at least 8 hours or up to 24 hours. (The resting time softens the seeds and ensures a creamy consistency.)
- 2. Measure out 1/2 cup (118 ml) vinegar and mustard seed mixture and set aside. Combine the remaining vinegar and mustard seed mixture, sugar, and salt in a small food processor or use an immersion blender and process until coarsely ground and thickened, 1 to 2 minutes, scraping down the bowl as needed. Stir in the reserved vinegar and mustard seed mixture.
- 3. Using a funnel and spoon, portion mustard into two 1 cup (237 ml) jars. Cover and let the mustard stand at room temperature for 1 to 2 days to allow the ingredients to meld and develop a well-rounded spiciness. The longer it rests, the spicier it gets. Taste it often and once the desired spiciness has been reached, refrigerate and serve. (The mustard can be refrigerated for up to 6 months; once refrigerated, the flavor will continue to mature but will not become more spicy.)
