Acorn Acknowledgement; ‘Nuts as Staple Foods’ with Osker Brown; and More – for “The Creation of a Thousand Forests is in One Acorn.”

Acorns have great potential as a staple food. This may seem like it takes a lot of processing, but compared with conventional staple food sources with similar nutritional profiles and palatability, this and many other tree crops require less energy overall to enjoy, potentially require less capital as a cost-of-entry, and have numerous co-benefits. This calls for a different culture however, as there’s a shift in where much of the energy is expended in enjoying regional nuts and trees for basic needs:

In conventional systems, energy use and negative externalities occur “Not In My Backyard“, in rural areas and in far away oil and fertilizer producing places. In systems offering greater food sovereignty, resilience, and positive externalities, energy use is brought closer to the point of consumption and after the point of sale.

Shelf stability of acorns highlights a trade-off of this shift in the point of energy use to enjoy the crop: acorns and many nuts are very shelf stable, but when they’re processed enough to be ready to eat (e.g. as acorn tortillas or roasted hazelnuts) they become less shelf stable. This is not a critical issue, as acorn flour and many value-added nut products can last for weeks dried or refrigerated and be preserved for months or maybe years frozen. This trade-off affects the culture of use and markets for local nut crops:

Tree nuts are long-lasting, resilient, more intimate staple foods which require more labor close-to-home, but

tree for basic needs also bring home closer with the source of one’s well-being and being well in ecological mutualism with that which supports oneself.

And with this in mind, I give thanks to Osker Brown and Living Web Farm for the information below about acorns for landscapes and livelihoods.


Distribution of time for tasks to enjoy acorns:

  • 1/3 labor gathering and drying
  • 1/3 labor cracking, leaching, processing
  • 1/3 labor quality control, removing nuts with signs of mold

Gather & quality-control red oaks, dry, store in-shell . . . here is a very informative video series, starting specifically at part 5 which details home and community-scale acorn gathering.

Ready to prep for meals? De-shell red oak acorns using hammer, nut cracker, nut crucible…or for large home-scale (e.g. ‘5lbs batch weekly for two months’), Davebilt #43 nut mill has been found effective and robust.

Sort and quality-control, winnowing kernels from shells. Discard kernels that are not a shade of brown whether dark or cream colored, e.g. remove nut meat colored white, yellow, green, or blue), discard shells for mulch or fuel or tanning.

Leech (various methods) until astringent flavor is no longer noticeable when tasting nuts. Dry. Break down further into flour using food processor or similar methods. To begin with cut with 50:50 all-purpose flour and use as you would all-purpose flour. Acorn flour can replace all purpose flour for many recipes.
