Foie gras and truffles are a combination as naturally decadent as can be. Smooth and creamy duck foie gras is whipped up with duck fat and Armagnac wine, then studded with aromatic black truffles. Serve it chilled, paired with toast or a simple crusty bread, with some garnish of cornichons, a sprinkle of sea salt, a touch of Dijon mustard, or a sweet jam or chutney.
