Consider how you plan to use your shelled acorns
At this point you need to pause and make a decision about how you plan to use your acorns. There are two types of leaching: hot and cold, and which one you choose depends on how you plan to use the acorns.
You use cold water leaching to make acorn meal suitable for baking. The cold water preserves the starchiness of the acorn meal, which makes it work well in breads and pancakes and muffins and such.
Hot water leaching removes the starch, but seems to bring out the nutty flavor more, which makes it better for using the acorns in savory foods, like acorn burgers, or, in sauces. People have concocted acorn sauces to serve with game, which sounds wonderful. Basically, it seems like this process is the best way to go if you plan to use the acorns as nuts. It seems like you could substitute them for recipes which call for hazelnuts. The pudding, for instance, was a tapioca pudding in which the the cream was first infused with acorns, and acorn meats were folded into the pudding.
You can also choose to store the meats at this point, unleached. You can dry the meats out in a dehydrator or low oven, then put them in a container until you need them. At that point you will want to soak them to soften them up for grinding.
You asked about acorns, there ya go. If you want more info on the leaching (yes, it's leaching, lol) processes individually, let me know.
Remember, read read read.
TLDR: acorn info for food prep.
