i'll have to look up the web page where i read about making acorn flour,
actually, the processing isn't that involved, no more so than cooking. as i
recall, the indians who used the acorns would grind them up, then put the
acorn meal into a bag and leave the bag lying in a stream or river for a
day. the cold running water would take the tannins out of the acorns. then
just dry out the meal, and use it.
i will check, and get back with details.
