You found a decent recipe for acorns? That is impressive. I've noticed among the many efforts to preserve and revive native people's culture, eating acorn meal never seems to be part of it. Live oak acorns was the major food source for native people in California for long periods of time. This is the first I have come across someone trying to eat them today. Your first few failures is what I expected as well as your resounding... meh in granola. The fact that you got something better than meh is impressive.
