    I’ll see what I can do! The water is now totally clear but the acorns are still bitter. I am trying to figure out if somehow I bound the tannins in when I dried them. I have no clue. I will try the hot leach method and see how it goes. Thank you so much for your quick responses.

    Thanks for a great website. I am glad the Pittsburgh Tribune Review did the article on foraging. Too bad it’s too late in the year to collect white oak acorns this year, but in a ten minute walk in downtown Ambridge I can probably collect a bushel bu next fall. I can’t wait to try some recipes from here and the newspaper. The flatbread recipe sounds like something I would love as I eat nuts and homemade breads often. One question: Can I use my bread machine for any of this?

    Wanted to add a tip about where to get those gallon jars cheaper. Buy those huge jars of bad pickles sold in big supermarkets. The pickles are usually so poor quality as to be inedible but the whole jar only costs between $6 and $8 dollars depending on where you go.

    I live in Northern California and I did this last year collecting mostly Coast Live Oaks. The first time I tried it, I just threw acorns in a five gallon bucket, then brought them home to sort. When I got home, that is when I noticed that 80% of them had worms in them. I tried shelling them and just saving the good parts and it took hours to just get a quart. So I went out again with a hammer and some Felco pruning shears. The hammer was tedious but the Felcos cut the the acorns in half easily, so I did the sorting in the field. This time I got 3 gallons of shelled, halved acorns in about 3 hours or about the same time it took me to get a quart my first try. The added benefit was the acorns were already halved and when I got home(sorting already done) all I had to do was add water to the bucket to start the leaching process. It took 12 days of leaching. I would also recommend nylon paint strainers instead of cheese cloth. They are super durable and ultra fine and you can squeeze the heck out of them without destroying the fabric weave. Somebody suggested that I could load up a couple of gallon paint strainers with crushed or blended acorns, tie them off and drop them into the toilet tank reservoir. That way every time you flush the toilet clean water is run through the strainers to start another leech. I think you would lose that fine starch but if you gathered a lot it might be worth a try on a small batch. . .
