Before the arrival of European culture, they were a staple food for the natives of Eastern North America. They have since declined in popularity. The problem with acorns lies in the tannins they contain which render them extremely acrid and bitter, as well as somewhat toxic in quantity. In order to make them fit for human consumption, the tannins must be removed. The Indians had several ways of doing this. The simplest was to chop the kernels, and boil them in several waters to leach out the acrid principle. Sometimes wood ashes were added because the tannins were more soluble in basic solution. Another method was to scoop a hole in the sand, place the chopped kernels in the hole, and let cold water trickle through the mass for a few days. This practice resulted in heavy wear on the teeth from the sand which was inevitably recovered with the leached acorns. Acorns were eaten mashed into a soup or gruel, cooked as an unleavened bread, and probably combined with other foods. Flour was made by drying and grinding the processed kernels. Acorns vary considerably in tannin content. Those from the white oak group generally have less than the fruits of the red oaks. The white oak group can be told from the red oaks by the leaves. Those of white oaks have rounded lobes, while the leaves of the red oaks usually have pointed lobes, with a hair of bristle at the end. The Indians somtimes ate the acorns from the white oaks without any processing, but even these are apt to be unpalatable and bitter to a palate accustomed to wheat bread. If anyone is feeling adventurous, I can suggest the following procedure. Collect acorns from white oaks if possible. Shell, and coarsely chop the kernels. One nice thing about acorns is the high meat to shell ratio (compare black walnuts). Put the chopped meats in a pot, cover with water, bring to a boil, and simmer for 15-20 minutes. Pour off the water, and repeat the process twice for a total of three times. Dry the meats in a slow oven (250F), and grind in a mill or blender to about the consistancy of cornmeal. This can be used like cornmeal, mixing half and half with all-purpose flour to make bread or muffins. The result is very dark, almost like pumpernickel, and has a distinctive "acorn" flavour. I thought it was interesting, but nothing to rave about, and still a little bitter. (Euel Gibbons on the other hand has great things to say about the flavour and nutritive value of acorn bread). I suspect however, that a lot of nutrients get leached out along with the tannins. Have fun. Perhaps for an authentically traditional Thanksgiving dinner... Randal Nelson (nelson@cvl)
