Not sure if this board is appropriate but I have a query. My friend has multiple black walnut trees loaded with nuts and is throwing bushels of them away---she thinks they are trash. Yikes. No other nut has such a flavor for baking but as her trees are never sprayed I wonder if they would be wormy. I remember my Grandma's black walnut tree which I doubt was ever sprayed and the nuts were fine. Does anyone happen to know the probability that unsprayed black walnuts would be OK vs wormy? Because if these nuts are good I am going out there (it's some distance) with a very large basket and spend the winter picking nuts out of their shelves, a brutal job but worth the effort.
