I have some walnuts which were picked up from under a local tree, left to dry for a while, and shelled. They look moderately old, but haven't become shriveled or gone moldy. Some have a kind of bitter after taste when eaten raw (unpeeled). Does this mean they are too old, or is it normal?
Will they have the same flavour when cooked?
I'm not sure whether I should cook something with them, or whether I should discard them.

None of these are absolute, but together they give you the best indication that you can probably get at home.
I found several anecdotal accounts that the float test, also described by MaxS (the nuts should float in water) will help separate bad nuts, but I could not find credible documentation.
