Bar-le-duc jelly is a highly regarded preparation of jelly originally composed of select whole seeded currants, typically white currants or alternatively red currants. The name Bar-le-duc refers to the geographical origin of the preparation in the French town of Bar-le-duc. Since the jelly's first documented reference in 1344, the culinary name "Lorraine Jelly" is occasionally used, as the city of Bar-le-duc lies within the boundaries of the former province of Lorraine.
Commonly served as an accompaniment to game, spread on bread, or with foie gras, it is considered a culinary luxury, sharing an elite status akin to Beluga caviar and is colloquially referred to as Bar Caviar. The typical product is a jam, with the berries remaining intact in a thin syrup. About 200 currants go into one 85 gram jar (approximately 3 ounces).
