OK, maybe it is not really a fad. Not here in Germany that is. But almost 6000 years ago the Kosher food “movement” (everything is a movement now) started. It still exists but has a big brother, Halal. The two dietary systems have much in common which shouldn’t be surprising considering the shared roots of Jews and Muslims (and Christians). Funnily enough, following these food customs is something that can bring Jews and Muslims together in a place like Central and Northern Europe that barely acknowledges non-pork fare in most restaurants.
