When I was a kid, we had a huge black walnut tree. Because she didn't want us to get stained, Mother never would let us do the hulling. I don't remember anyone stomping on them to remove the hull, but I also don't recall what method they did use. Seems like on the farm there was a tool for every purpose. I also don't remember scrubbing the nuts after hulling, but I can't say for sure that they didn't. I think we just let them dry and cure, then we shelled them as needed. Now mind you, it's over 50 years since I was involved with the process, and some of my meds give me brain fog. If I can remember what I did yesterday, I'm doing good. However, I would trust the information in this article since the author was actively involved in the process, and she backed it all up with photos. /img/vbsmilies/smilies/thumb.gif
