The article brought home a lot of memories as a kid. We had two black walnut trees in our back yard and every year we’d gather up the fruit and hull the nuts and crack the shells. I had stained hands for weeks.
Good memories. I remember using a vice in dad’s workshop to open them. IIRC, if you lined up the seam, they opened fine. A lot of work for the meager harvest!
Delicious in banana bread.
