I got the honey from the farmers' market at the train station in Kensington (Saturday mornings til 12:00). I'm not sure if the guy still sells there; I've been out-of-town for a while.
Here's the website. I don't see the blackberry honey listed. Maybe they'll have after the blackberries come into season?

It's really has a delicious taste. Thanks so much for the cheese pairing and scone suggestions.
