Acorn Flour!

I found this post about making acorn flour. We've got billions o' acorns up in this block-and-a-half street I live on, as I discovered when I gathered a bunch for crafting last year, and I think I'd love to give this a try. Mostly because of the following:
a) acorns are so pretty-- the shape of them is something that speaks to my hobbity soul, and the color of these inside is like saffron (i wonder if it'll stay yellow?)
b) people who lived here before Europeans lived off the things, and so can I
c) it's this huge resource that isn't getting used. I mean, this is an Arbor Day Tree City, and most of those trees are oaks.

I'll keep you posted, yeah?
