The rule for picking out high quality blueberries or blackberries is largely the same: if they are even a touch red or burgundy, they aren't ripe enough to eat. Blueberries should have a deep cobalt shade closer to the color of slate than a blue jay, and blackberries should be a deep enough purple that they could pass for black to an untrained eye. If you're feeling adventurous, the blueberry-blackberry pie would also be just as tasty by substituting in elderberries, mulberries, or gooseberries for the blackberries in the dish.
