Combine the minced duck confit with the shallot, savory, pepper, egg, and breadcrumbs in a small bowl and mix well. Scoop out small amounts of the mixture (about a tablespoon or so at a time), and roll into balls, tucking a cube of foie gras in the center of each.
Heat the fat in a wide skillet until shimmering, then add the meatballs, turning them gently to brown them on each side. Remove them to a paper-towel lined tray once they are browned all over.
Combine the white balsamic with the fig jam and mustard seeds in a small pot and cook over medium-low heat until thick and syrupy, stirring often. Add a few grinds of pepper, then add the meatballs and toss gently to coat, cooking until they are nicely glazed and sticky.
Carefully remove each meatball and wrap with a slice of the duck prosciutto, using a toothpick to secure them. Place them on a foil-lined sheet pan and broil until the prosciutto is crispy and browned and the glaze nicely caramelized.
Serve hot with your favorite cocktail or a chilled flute of bubbly. Feel decadent. Don’t apologize.
