News from Native California;Fall2005, Vol. 19 Issue 1, p26
This article presents information on a hot spring leaching technique for acorn and plum seeds. A variation on the customary hot springs leaching technique is the alternate processing method in which acorns were put into fine, hand-wooven net bags tied with rawhide place into a stream. The running water causes acorn shells to split open and release most of their tannic acid.
