We had black walnut trees on our farm in Wisconsin. We would collect buckets of them and spread them on the driveway. The cars and trucks would break the hulls. We would later pick them up and lay them out on the floor of the back porch to let them air dry.
Great idea thank you for the support.
I have processed so many black walnuts that way -- and my parents, and their parents. It is such a traditional way to get those hulls off. And lots of fun for everyone. I have such happy memories as a kid doing that with my granddad in his driveway that sloped so steeply. There was always so much commotion and clutch work, lol. And all the neighbors were doing the same thing.
