This sounds really good! I've had mint hot chocolate and love it; sometimes
I grind some cinnamon or mint into regular hot chocolate. I still have some
of those spice mills that Braille Gift Service used to sell; tey were little
plastic containers of unground spices and you turned the top to grind what
was inside and it came out the bottom. When the spice was gone, you just
shrew away the container; trouble is, I don't have a source for them any
longer, but what I've got left is really neat.
