title_body: So I got some roasted beans wet, how to dry them?
upvoted_answer: I would probably throw them out - I would just roast more - but I might also try and spreading them out on a flat tray that fits into the oven and turn it up to 200F (or lower) and let them sit in there until they are dry again. Just keep your eye on them and check frequently. If you start to smell them, they are probably past dry.
  
  No idea how that will turn out, but my wife does a similar thing with crackers that have lost their crunchiness.
