Cool! I've been into mixing only one or two other flavors with my tobaccos lately, as to not mask the flavor of the tobacco very much. Sounds like this Taro might be a good replacement for 5% acetyl pyrazine, if it lends a nutty quality to the mix.
On a side note, why the heck is taro like the most used vegetable all over the world, but has never, ever hit a dinner table in the USA? It looks outstandingly nutritious, according to the specs.
