I agree with Todd, Plan B is the way, but I use white corn meal instead of blue. Even before that I take the LIVE softshell, using a pair of kitchen scissors cut off the head and eyeballs. With my hands, remove the sex flap and parts on the bottom, lift up the two ends of the top shell, remove the book lungs and then prepare them as Todd does in plan B. There just isn't enough flavor to over power the smoke.
Don't eat any softshells that won't move, unless You (YOU) froze them alive. Someone else freezing them could include some dead softshells and they can make you dead.
