Yes, or in front of a Fan or in the Smoker at 130*F for 1 hour...You want the casing to be free of excessive moisture and to form a bit of a pellicle but not dehydrate. If too wet the casing can get Streaky. Not a major issue, just not Pretty. Additionally, wet casings can pick up a variety of substances in smoke that leads to off or bitter flavors...JJIsn't it true you should hang sausages in a cool place to allow them to dry for a bit before smoking?
