Dark Mustard

2 tsp. horseradish powder
2 Tbls. mustard powder
2 Tbls. whole mustard seed
1/2 tsp. smoked salt
1/4 cup cold water
1 Tbls. molasses
1 Tbls. balsamic vinegar

Coarsely grind the mustard seeds in a mortar with a pestle. Combine the horseradish, mustard powder and seeds, salt, and water, and stir thoroughly. Let it sit for 10 minutes. Stir in the molasses and balsamic vinegar. Let cure for a day before using.

This is a really strong mustard. For the sharpest, darkest mustard, use brown or black seeds. The mustard shown here used white seeds.
