It occurs to me, the label "bread" is attached to products made from a number of vegetables, not just grains. "Bread", leavened and unleavened, can be made from many starchy fruits or roots, as we Trolls have discovered. So, what did the baker use to make her fresh-baked bread? I don't recall seeing any large grain fields surrounding the Sun Village.
Reminds me, we rented "Children of the Corn" this weekend - Yes, it is "corny" by modern standards!
