You can also make flour with the roots or pollen of '''cattail''' and with '''acorns'''. Though acorns may be found in abundance, it ''is'' a lot of work to process it into flour. Other nuts (walnuts, hickories, hazelnuts, etc.), though often less abundant, are a little easier to process into flour as they do not require leaching to remove tannin. See the answers to the [[AY Honors/Edible Wild Plants|Edible Wild Plants]] honor for details.
