K.L. Keller mustards all start the same way: with real mustard seeds (not powder) and real vinegar (not added citric acid and water).

However, this particular mustard is special. Named Grand Champion of the Napa Valley Mustard Festival 2009, this Dijon incorporates black truffle pieces and black truffle essence to fully capture the truffle flavor.

Use on a grilled beef sandwich, pair with poached chicken or bratwurst, or even use in a vinaigrette dressing atop a fresh salad.

Ingredients: water, mustard seed, white wine vinegar, salt, black truffle powder, porcini powder, citric acid, truffle essence.
