Hi All, I'm about to try curing salmon for the first time and was wondering about duration. I've seen everywhere from 24 hours to 5 days, so not sure how long to go. After reading some other posts, it seems like the only effect duration has on the fish is that it just gets saltier/richer. Is that accurate? Also, is there a minimum amount of time before the fish is "safe"? And finally, do other fish work just as well as salmon? Thanks!
