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.
And fudge.
Nashville House in Nashville, Indiana does a landoffice business with black walnut pie (like pecan pie but better) when in season if they can get enough of ‘em.
We had a cutting board and a hammer to open them.
