Yes, very sensible. You will get a much more predictable and quality end result if you do, also a nicer colour and mouth feel to the cured sausage. I use a bacterial starter culture too , it insurers that the first fermentation phase goes according to plan ( a bit like making a sour dough bread or brewing beer ) I’ve found Weschenfelder to be a great supplier of all the necessary fermentation and curing ingredients. When I’m stuffing the casings I take a little of the sausage mix and wrap it in clingly film to enable me to check its ph before and after it’s time in the warm and damp fermentation chamber , Once fermentation is over I then sling that bit and make a note of the ph. After curing is completed , in about a months time, I harvest the completed sausages from the curing chamber and check the final ph then too, prior to poring a drink and eating some with some freshly made rye bread etc.
Post pictures of your results and I hope you have a happy time making and eating them.
Kindest regards, Olaf
