Hello all, been away for awhile & am preparing to do my 1st homemade sausage project this weekend. I inherited all the right tools from my grandpa this summer before he passed away - Grinder ,stuffer,"sausage maker" smoke house , Rytek Kutas "Sausage Bible" ETC. . I'm pretty confident on being prepared in all aspects of the process except for the "linking" part. I have found no real clear cut answers on what Exactly to do . I have seen one video that made sense & looked efficient to me where your 1st link coming out you twist one way , then the next twist the opposite & so on & so forth till the end.... but should you use twine to tie off also , or can you just knot the casing themselves? & if you do use twine , after ( im assumin you cut the links) do the casings stay "crimped"(not sure that's the word i want ). oh btw, this is fresh polish kielbasa w/ natural casings.Thanks in advance for any help . hoping for as good of results as my grandpa always had.
