MAKES: 11/2 cups
TIME: 15 minutes, plus a day or two to soak the seeds
If you’re a mustard enthusiast, you’ll be amazed by how easy and cheap it is to make your own and how good it is. You can customize the flavor in many ways with minor adjustments; see the list at right. The only rule you must follow is to mix yellow mustard seeds with brown or black; otherwise the results will be too harsh. And if you use red wine instead of water, expect the color to be a deep reddish brown.
1/4 cup (about 11/2 ounces) yellow mustard seeds
1/4 cup (about 11/2 ounces) brown or black mustard seeds
1/2 cup red wine or water
1/2 cup sherry or malt vinegar (or any vinegar with at least 5 percent acidity; see Types of Vinegar)
Pinch of salt
Put all the ingredients in a jar with a tight-fitting lid or another sealed glass or ceramic container. (Don’t use metal; it will corrode.) Shake or stir, then set aside to soak for a day or two.
Put the mixture in a blender and pure for several minutes to grind, adding a little extra water as needed to keep the machine running. Stop and scrape the sides down once or twice and repeat. You’ll never get the mustard as smooth as Dijon, but you can vary the coarseness by how long you let the blender run.
Return the mustard to the container and cover tightly. Store in a cool, dark place (or the refrigerator) for up to several months. The mustard will be quite sharp at first but will thicken and mellow with time.
Variations
Port Wine Mustard. Instead of the red wine or water, use 1/2 cup ruby or tawny port.
Brewhouse Mustard. Instead of the red wine or water, use 1/2 cup strong-flavored beer, like stout, porter, bock, or dark or amber ale.
