Enjoy the crunch of the soft bursting mustard seeds. Whole black mustard seeds bring spice and pungency to this traditional French mustard while the whole seeds, preserved in vinegar, give the mustard its most prized quality. Use it like regular Dijon mustard, as a condiment for grilled meats and sausages, a flavouring in a marinade, sauce or salad dressing, or to make a delicious crust for a roast leg of lamb or prime rib!
