@Doug-Kapfenstein Yeah like @Parksider said, that’s a very long time, shouldn’t need more than 20 minutes. Hanging them might help dry them out but I think your casings are going to continue to separate from the meat, once you get some moisture in there it is usually not reversible.
You could simply peel the casings if hanging them doesn’t work? Wouldn’t have the snap and they would look a little odd but shouldn’t affect the taste much, if at all.
