When I was *very* young, I had no idea what "kosher" meant. I knew about Catholics, about holy water, about how holy water is "created", and about what Hollywood says holy water can do. And about the only "kosher" food I ever noticed in grocery stores was kosher salt. And somehow, I got the Catholic and Jewish ideas mixed up in my head as a young boy. It went something like this...
Imagine a food manufacturing / distributing plant. All types of food rolling along on conveyer belts, preparing for packaging and shipment to all points. Exact same food as what gets shipped to other, gentile grocers. Only at the end of these conveyer belts stood a very Woody Allen-esque Jewish rabbi, saying yiddish prayers and sprinking salt over the food as it rolled by, thus making it kosher.
No lie, that's how I used to think Kosher food was made.
