You might try Leonidas. I'm not a fan of dark chocolate, but their milk chocolate is to die for. Our local store imports it weekly from Belgium. It's made without preservatives. I get the dark chocloate for my best friend. She says it's really good. At $25 a pound it better be.
I found this atthe Lindt site, but I don't think it's what you had.
Good luck in your search!
