I've been thinking about this a lot. I love the Smilin Menthol from V4L, which I really didn't expect to like much at all, but the stuff tastes like an Andes. I want to be able to replicate it
through TV if I can figure out how to do it.
My ruminations thus far have suggested you would need
three major flavors to do it right: sweet milk chocolate, mint, and a little menthol.
This is coming from somebody who's never mixed anything, so I could be missing out on something. I don't know if sweet milk chocolate is in the cards or not, but if not maybe you could use a standard chocolate (not mocha) and add in a little dairy/cream and sweetener if necessary?
In my head I'm thinking 2 parts chocolate (%40), 2 parts mint (%40) and 1 part menthol (%20). Dunno if that would balance or not, kind of hard to guesstimate when you've never mixed the flavors.
I'm seriously considering buying the requisite single flavors and experimenting until I find the proper recipe, then give it to Geoff and see if he'll pre-mix it for sale. After I figure it out I don't mind doing it myself, but I imagine a lot of people would be interested that don't want to muck around with mixing.
