Kathy sent me this link http://www.sanaturalareas.org/acorns.html.
I followed the steps, but boiling them until the liquid is clear has taken way more than 2-3 hours.
I collected & dried them on Easter. I de-shelled them on that Monday. I believe the following day I started boiling them after work & soaking them. Here it is a 1 1/2 weeks later and they still do not appear ready to dry & ground to make into meal.
I was brave and tried a teeny taste a little while ago. It wasn't bitter but had kind of a mushroom-like taste (they also smell like mushrooms when the are boiling).
Hopefully I can finish them tonight because I am going out of town for the weekend.
