Sharon, I have never heard that story of Pluto and Menthe. Very nice. I will think of it every time I work with my mints.
This last year I was on a mint kick, trying to get all the flavors! I have peppermint, spearmint, orange mint, chocolate mint and pineapple mint. I still never found apple mint but I'll get it eventually.
I didn't realize I could use mint in my pantry. I had a real problem earlier this year that took three emptying of the pantry and pitching and scrubbing before I finally got rid of the cupboard moths! I did hang rosemary but heck, I have lots of mint I could have used.
I don't even know what goes into a mint julep but it sounds so refreshing!
