One of my most memorable Torah lessons from elementary school was the one about the manna. This was the magical food that the Jews ate while traveling through the desert. It was some kind of amorphous bread that fell from heaven daily, and the Torah describes it as being like honey wafers. Part of the magic of the manna was that it could taste like whatever one wanted it to. And this is where the imagination of the wide-eyed child was piqued: If you were thinking about pizza, the manna tasted like pizza; if you were thinking about a thick, juicy steak -- well, you get the picture.
