Alstertor "Dusseldorf" Mustard

Düsseldorf mustard is similar to Dijon mustard, but it tends to be somewhat more pungent than Dijon, being made with vinegar instead of verjuice, with a darker overall color. The flavour can range from milder, to hotter than Dijon, to quite hot, depending on the mustard seed used. Either brown and white mustard seed, or decorticated black mustard seed might be used.
