Ingredients

2/3 cup yellow mustard seeds 

1/2 cup brown mustard seeds 

1 cup red-wine vinegar 

1/2 cup dry red wine 

1 teaspoon freshly ground black pepper 

2 tablespoons sugar 

2 teaspoons salt 

1 tablespoon dried marjoram 

Same ingredients as Green Peppercorn, but substitute 2 tablespoons pink peppercorns for green, white-wine vinegar for balsamic, and add 3 tablespoons chopped fresh tarragon. 

1 cup brown mustard seeds 

1/4 cup yellow mustard seeds 

1 cup dark beer 

1 1/4 cups white-wine vinegar 

1 cup mustard powder, combined with 1 cup water (let sit 20 minutes) 

1 teaspoon sugar 

1 teaspoon salt 

1 teaspoon ground allspice 

1/4 teaspoon ground turmeric 

1/4 teaspoon ground mace 

1/2 cup yellow mustard seeds 

1/4 cup black mustard seeds 

1/2 cup dry sherry 

3/4 cup balsamic vinegar 

2 tablespoons green peppercorns 

1/3 cup olive oil 

2 teaspoons salt 

Preparation

In a nonreactive container, combine mustard seeds with alcohol (beer, wine, or sherry; according to recipe) and vinegar. Let sit 48 hours. Check periodically to make sure seeds are covered by liquid; add more if necessary.

Transfer seeds and liquid to a food processor. Add remaining ingredients. Process until seeds become creamy, 4 to 6 minutes. Store in an airtight container in the refrigerator for at least 1 week before using to let the flavors develop. The mustard will keep for up to 1 month.
