I have been fascinated by acorns for a long time now.
I have watched squirrels running around with them in their little mouths and it is my understanding that even the Jay Birds like them.
Somebody told me once that the earliest Americans prepared acorns into a “Meal” or a “Flour” and used them as food.
I learned that before an acorn can safely be eaten by a human being, there is a long and complex ritual of leaching that has to take place and if the process is not followed, the acorns are poison to humans.
There is a set of instructions on the web purporting to teach us how to prepare acorns for cooking ….. https://www.almanac.com/content/how-prepare-and-cook-acorns
I have not ever tried preparing acorns and apparently the animals and the birds see no need to prepare them.
I went looking for a commercially prepared acorn meal at the health food specialty stores once but it seems that no one has ever thought to prepare them, mill them and offer them for sale to the market. I can’t even find any recipes that one might use in preparation of acorns.
Like I said above, acorns are toxic if not prepared properly and so there are more instructions on how to deal with acorns at “Wiki How” —– https://www.wikihow.com/Use-Acorns-for-Food
There is an extensive article about acorns at Wikipedia and the following is an excerpt from that article. The entire article may be read at: https://en.wikipedia.org/wiki/Acorn
Wildlife that consume acorns as an important part of their diets include birds, such as jays, pigeons, some ducks, and several species of woodpeckers. Small mammals that feed on acorns include mice, squirrels and several other rodents.
Large mammals such as pigs, bears, and deer also consume large amounts of acorns; they may constitute up to 25% of the diet of deer in the autumn. In Spain, Portugal and the New Forest region of southern England, pigs are still turned loose in dehesas (large oak groves) in the autumn, to fill and fatten themselves on acorns. Heavy consumption of acorns can, on the other hand, be toxic to other animals that cannot detoxify their tannins, such as horses and cattle.
I am a peanut, walnut, hazelnut, filbert, hickory nut person myself, but like I said before, I would love to find a way to try something prepared from acorns somewhere along the line, sooner or later.
