Just started making beef jerky and snack sticks. Made about 4 batches so far. Cant say I have been overly impressed with the end results. That is why I am here, trying to gain knowledge to make a better snack stick. Having trouble getting my collagen casings to stay tight on the meat after smoking. Tried an instant ice water bath but the casings still seems to sag on the meat. Any suggestions would be greatly appreciated.
