Spicy German Mustard

This mustard accompanies my soft pretzel recipe, both of which were made this past week for an Oktoberfest party.  I was amazed with how easy this process was - soak the mustard overnight in a few spices and vinegar, then blend.  Good lord, why have I been buying mustard at the store?  I know one reason - I hadn't felt like chasing down two different colors of mustard seeds until I decided that I had to try this, at least once.  And now mustard seeds will become a staple in my pantry, because I want to be able to make this at all times.

I thought this mustard was tasty - a bit tangy, slightly spicy, just a hint of sweetness.  I was expecting a darker, sweeter mustard, so I might tinker with this a bit to adjust the flavors to what I was hoping for.  But this was delicious in its own right, so I'm excited to pass this along to everyone with the pretzel recipe.

Makes about 1 1/2 -2 cups

• 1/4 cup yellow mustard seed
• 2 Tbsp. black or brown mustard seed, heaping
• 1/4 cup dry mustard powder
• 1/2 cup water
• 1 1/2 cups cider vinegar
• 1 small onion chopped
• 2 Tbsp. firmly packed brown sugar
• 1 tsp. salt
• 2 garlic gloves, minced or pressed
• 1/2 tsp. ground cinnamon
• 1/4 tsp. ground allspice
• 1/4 tsp. dried tarragon leaves
• 1/8 tsp. turmeric

In a small bowl, combine mustard seed and dry mustard. In a 1- to 2-quart stainless steel or nonreactive saucepan, combine remaining ingredients. Simmer, uncovered, on medium heat until reduced by half, 10-15 minutes. Try to be patient and cool the mixture as much as possible before pouring over the mustard mixture; it turns out that both heat and acid will dull the pungent heat developed by mustard seeds, but my guess is that heat will do it faster, while also killing a lot of the flavor.  From About.com:

"It is the chemical reaction between two compounds, myrosin and sinigrin, that combines to turn up the heat when the cells of the seeds are broken and mixed with cold water. "

So my suspicion is that the use of cold vinegar will allow for a slow reaction between these compounds for a while, but eventually it gets in balance, and can be kept refrigerated until the reaction peters out, yielding a stable final product.  If you want to experiment with this (and you can bet I do), try soaking two small quantities in water and vingear, pureeing both and tasting the difference.  I also plan to try experimenting with warm vs cool vinegar liquid poured over the seeds, as well as the total soaking time, to see if these things make a difference.

Anyway, let mixture stand, covered, at room temperature for 24 hours, adding additional vinegar if necessary in order to maintain enough liquid to cover seeds.  Process the seeds and mixture in a blender or food processor until pureed to the texture you like, which can take at least 3 or 4 minutes.  If it gets too thick after a few days, stir in additional vinegar.  Scrape mustard into clean, dry jars; cover tightly and age at least 3 days in the refrigerator before using.
