My first attempt to leach the tannins out of white oak acorns was a disaster because I tried to boil them out. The heat locked the tannins in and I could not get them out afterward.
My second attempt was two days ago with leaching tannins out with cold water. Much better, and made a delicious acorn flour cake with raisins last night. A little astringent flavor did remain, but I only leached the acorn puree for 4 hours. Next time I'll do it for much longer and see how that turns out.
