I picked up 65 black walnuts yesterday. It took like 2 hours to get 32 hulled, oooh boy. Hope it's worth my time.
I also got a bunch of rose hips. The bigger ones I tried picking at the beach went bad too quickly, but these smaller ones that are less rotund shaped seem better. My Asian market has gobs of rose hips growing.
Also, Concords, I'm picking the last of them. Actually make a very good grape juice. Like nice and extremely strong tasting. I boiled 1 cup grapes per 1L water. Turned out fantastic. I plan to gather the most Concords possible and then freeze them so I can have high quality grape juice all year. Hopefully my homemade rosehip tea turns out nice, too. I bought some at the Polish market just so I could make sure it'd taste good, and I like it. So homemade should be good, and cheap, too. Woohoo.
Black walnuts you can make a machine to hull them, but I think I'd only do that if I had my own tree.
