BTW, that reminds me.

The acorns, once boiled free of tannins can be dried, shelled and ground to make a flour for breads and cakes that is supposedly quite tasty. At least the Native Americans thought that to be so.

They served it with venison stewed in maple syrup. At least that is according to one menu that I read years ago. Spices included 'greenstick' or sassafrass.
