So (mainly cause I got tired of apple) I pulled a sample of my other tobacco mix that I hadn't tried yet. This was basically the same recipe as before, except it uses Cap Caramel instead of TFA RY4D, and it doesn't have the chocolate in it (so it is truer to the original recipe I based it on). This probably needs more steep time, I'm not really digging it. Tobacco was stronger using RY4D instead of caramel and I'm finding I actually like that better despite not usually being a fan of tobacco as a standalone flavor. And there's some flavor in there that isn't playing nice with the others, I think maybe it's the pecan. Maybe that will steep out, but I'm kicking around the idea of reducing the pecan next time I make this. Maybe 1-1.5% instead of 3%. And I definitely miss the chocolate, it goes well in this.
I'm also tinkering with the idea of adding a teeny bit of raisin. It could be disgusting, but I did say this mix reminds me of pipe tobacco. Aromatic pipe tobacco usually has a small bit of a raisiny smell. It might work.
