i was wondering about this, and i thought, you guys would be the people to
know.  i was reading awhile back, in a magazine, can't remember now just
which one, about native american indians in california.  it was about how
they maintained and nurtured groves of oak trees, sort of a segue into
agriculture, i guess you could call it.  they used the acorns as a staple
food item.  somehow, by soaking the acorns to remove the tannic acid, they
were then able to grind them into a coarse flour to use for making breads.
        does anyone know anything about this process, how to make flour out
of acorns?  are acorns a suitable neanderthin food?  i've got some nice big
oaks trees down the road here, so i could have a whole lot of acorns come
fall, if i had some way of using them.

        thanks, JoAnn.
