A long time ago (ten years I think) I had leather, mint and tobacco chocolates at the Fat Duck.
I've made pretty good tobacco ones, and I've been trying to work out how to do the leather ones.
My first instinct is to get some leather and isi infuse it into booze. Gold standard would be to rotovap that to get the flavor on its own, but unsurprisingly I don't have a rotovap.
1) Does anyone have any thoughts on how to do it?
2) what about the safety of leather. Eating chrome tanned leather is probably like using a plutonium fork. But what about veg tanned stuff?
3) is there a way to skip the leather completely and get the flavor some other way?
