Blueberries are okay, I think. The ones I have tasted from the supermarkets, here, seem insipid. I remember the ones I picked as a child in Nova Scotia being more tasty, but then I suspect everything was more tasty back then. It's possible -- probable? -- that the ones we buy are inferior to berries plucked fresh from the bush.

What you haven't tasted are huckleberries, a small, wild, prostrate relative of the blueberry that grows here in Virginia. Intensely flavored, they are what a blueberry ought to be but isn't.
