This is a great mod and I have enjoyed it immensely! I haven't been able to figure out how to deplete salt in order to get the empty salt shaker though - I've been making dried tomato slices, and that just consumes the salt completely. I also tried consuming the salt myself, and in either case, no shaker, which means I can't refill it with my rock salt ;)

Again, thanks so much for the amazing mod!
