Ah i see, I stuck a powered one together and it works, but I'd expected from the handbook to stuff aged meat and such into sausages, but perhaps thats "aging the sausage itself." I have the mods listed as compatible, but I can't actually seem to chop raw redmeat into nuggets, though fish nuggets work and show an actual recipe instead of a blank. The aged/cured ones didn't work when I tried and perhaps I missed the vintage sausage as well, and I'm unsure how this game works well enough to troubleshoot it.
