Yes, all acorns are edible, but they all require leaching before consumption. Many say "sweet" acorns (white oak group) do not require leaching, but note, all were traditionally leached before consumption.
Once the acorns are dried, they are stored in 5 gallon buckets with gamma lids. Fully dried acorns can last several years without going rancid.
I then run them through the DaveBuilt cracker, then pick through and shell what didn't come out through the cracker. The acorns are then milled and placed in a large bowl. Cover with cold water and let stand, changing out the water 1-2 x daily for 5-7 days, or until a taste brings out no tannins.
You can use the meal wet or dehydrate for flour. I then store the completed flour in the fridge in jars until needed.
Hot leaching only requires you to shell the nuts then boil 7-8 times replacing th water each boil. What I enjoy about this is although the nuts are a bit bland, you get the texture of a nut. Made a killer crisp topping with the hot leached acorns.
Besides baking, I utilize acorns for many areas of cooking. I use it for stuffing, polenta like meals, use in place of bread crumbs, batter for fish fry, and mini bean-acorn burgers. IF you are gluten free and use almond flour, acorn is a more sustainable replacement.
