Whip up a batch of homemade mustard, instead of looking for a substitute for dijon mustard! This mustard recipe is better than store bought and requires only a few ingredients.
Add all the ingredients to a small mixing bowl and mix to combine. Cover with plastic wrap and refrigerate for a minimum of 6 hours.
Transfer to a food processor or blender. Blend until your desired consistency is achieved. Add water, 1 tbsp at a time, if too thick to blend.
Transfer to an air tight container and store in the refrigerator for up to a month.
Notes
Note 1 - Mix and match between the two, in any ratio. Keep in mind brown mustard seeds are spicier than yellow.Note 2 - Replace with water if you don't have wine on hand.Note 3 - Substitution option: yellow or white onion.
