If you try this Leia, you gotta let us know how it is.
What else could you do this with? I've heard of vanilla beans, anything else?
I did it with 2 different flavored coffees and they both turned out great! One of them I can only do about 2.5-4%, but the other I have taken up to about 10% with good results.
You can do this with herbs, tea and I'm sure there are other things out there
