I had no idea black walnut was ever in demand. My sister wants me to save some chunks for her husband to use in his smoker. It will be a surprise gift for his birthday coming up in a few months. (And a gift that didn’t cost extra!)
I’ve tried black walnut for smoking and it gave meat a bitter taste. Kinda like when I use too much hickory in a long smoking session. I’ve learned to use mostly oak, plum from our big plum tree that finally died, apple, maple, etc.
Of course, over 80% of our trees are hickory...
