Crépinettes are minced meat (usually pork), in a crépine, the lace-like omentum from the stomach of a pig or sheep. The fat of the crèpine melts when cooked, and is less fatty than barde.
Hot pork crépinettes, cooked in white wine, are a popular accompaniment to a platter of raw oysters in Bordeaux.
