I've written before about the joy of climbing a mountain on a summer hike in Maine and taking a break to pick the tiny, sweet wild blueberries off of the bushes. They're so good.
The Atlantic with more about them. The writing is a bit convoluted in places, but it gives you some interesting info about these little blue pearls.
By the way, you can buy wild blueberries in many grocery stores--either canned or (better yet) frozen. Wyman's is the brand you should look for. Wyman's jelly is mentioned in the article.
On another subject, I hope to see you at the Ottsville Farmers' Market on Friday from 3-7 or at the Plumsteadville Grange Farmers' Market on Saturday from 9-noon. I'll be both places whipping up sample of tasty treats made from market goodies!
