Hi,
You just have to slice the roots thinly, and dry them in a dehydrator or a warm oven. Cool and store in an airtight glass jar.

thanks!!!

I grate mine, then put them in a very thin layer on a Craftpaper covered cookie sheet and dry it in the sun.
I like the smaller bit to use in making scent pots.

now, that is a great idea!
how do you keep from scraping off your knuckles? i never got the hang of a grater :)
