jpalma I don’t think doing this would give you the desired result. I think you would end up with a product that would have a tougher outside and not too much more smoke adhering to it. The cooking process has already been completed and the kielbasa has already been semi-dried, I think all this would do would be to further dry out the outer portion of the sausage. I also wouldn’t be able to say how long you would be safe keeping it in the “Danger Zone”. It’s already been cured so it is longer than 40 minutes but you also won’t be heating it back up to 160° so it isn’t that much longer.
Just my opinion but too many chances of something going very wrong to make it worth it.
