Acorns are much used by California Indians. They are bitter and need to be
sweetened. They are first pounded to a meal or flour. A wide basket is
filled with sand, which is carefully scooped away so as to leave a
basin-shaped surface; the acorn meal is spread upon this, and water is
poured upon it. The bitterness is soaked out, and the meal left sweet and
good.
