Decided to use a pre-made spice mix from a local butcher supply.
Stuffed into 19mill collagen casings I also ordered from Walton's.
Only had one blowout and I felt my first stuffing attempt was pretty successful.
Well below freezing here so I set the pid on my smoker at 36degrees and hung them to rest overnight.
In the smoker now with my amnps with hickory. Will post more when they hit temp.
