Recipe
1. 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.
2. 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
