My uncle has a vineyard planted on land that used to have walnut trees. He kept about 30 of the trees so he has access to a lot of green walnuts. One year we made Nocino with vacuum distilled brandy. This cutting up green walnuts and soaking them in alcohol. The results are OK but the liquor is too sweet for my tastes.
My hands were stained for a month from cutting walnuts.
I just ate a handful of walnuts before coming to the computer and reading this article. I had the taste of them in my mouth while reading the entire thing. It was a rather unusual experience.
Wait, I thought it was acorns that wore stylish berets.
And walnuts are also really good for staining wood. Got a piece of furniture with an ugly gouge in it? Get some walnuts (the eating kind), rub the meat of the nut (the part you eat) against the gouge, and watch it disappear. The physical damage will still be there, but the nut does a wonderful job of staining and blending the colors so it becomes almost unnoticeable.
