I was discussing the curing of salami and sausages with one of my teachers, who has been making both for over 30 years and he told me that when the meat is put inside the casing, spices and natural preservatives are also added. The sausages are then dried, he dries his for several months, in a cool, dry room. This is done to allow the spices to be absorbed by the meat and for the natural preservatives to prevent food poisoning. Otherwise they're just a bag of raw meat. The natural preservative is usually salt, but some other types of herbs can be used.
I was wondering if a similar mechanic could be added to the game, probably not so much the preservation but the drying. Maybe sausages should need to be dried for several RL days on a drying rack in a cellar?
