I ran out of the collagen casings the last time I made breakfast sausages so I formed the bulk meat into sausage size rolls with my hands. I put them in the freezer for an hour or so till they firmed up then vac sealed them. Freezing them first keeps them from being crushed by the vac sealer. Time consuming but it worked and my wife likes them better with out the casing.
@fallflight Yeah you absolutely need to add some water, that will help for sure! I’d start at 1 qt of water per 25 lb batch and go from there. Usually, 1-1.5 is a good amount but I’d recommend you start at 1.
