How to Make Mustard from Mustard Seeds
- 1). There are three widely available varieties of mustard seed from which you can choose: black, brown or white. White seeds will give you a yellow mustard and are the mildest of the three. Use brown if you want a Dijon style mustard, and black if you want a pungent taste.
- 2). Grind the mustard seeds into a fine powder. You can do this with either a mortar and pestle or in a food processor. Coffee grinders also work well for this.
- 3). Add water or vinegar to the ground mustard powder. Using water will create a very spicy mustard because of the way that water interacts with the powder. Using vinegar will create a mild taste. Do not pour the full amount in at once. Gradually add the liquid until it reaches the same consistency as store-bought mustard. You may not need the full quarter cup of water or you may need a little more.
