I get the point of the story but does the soaking method for opening walnuts actually work? Seems to me that you'd likely end up with a rotten nut.
It is a mixed metaphor, he refers to the problem as a "nut" but says after soaking the nut should open "like a ripe avocado"
Though I was confident this was just a metaphor, I did try cracking a walnut using this method. I submerged three walnuts in a jar with some tap water, and let them sit for three years before trying to open them.
It was a let-down: they were easier to open, but certainly not by hand, I still had to use a nutcracker. They smelled bad, too. I did not try eating them.
