I've been trying to create a salt flavor for quite some time. It's not impossible, because of how salt reacts with vapor, and our taste sensors, there's enough volume to emulate some saltiness. But I think it requires a specific volatile that's extremely concentrated to create this. The Five Pawns stuff is supposed to be salty, and it is, slightly, but not enough. Anyways, I know it can be done and I have been trying. I'll keep you update on my findings. As for chocolate, I feel like HS Australian Chocolate is the best. That's my opinion of course.
