We have the best ever blueberry crop to harvest this year.
The image gives you an idea why blueberries are perceived to be an expensive buy - although it has been pointed out to me that on a weight:cost ratio they are a lot cheaper than most junk food!.
Blueberries generally grow in bunches, similar in some ways to grapes. Blueberries do not ripen after they have been picked - so they need to picked ripe. A bunch of blueberries does not ripen at the same rate - these pernickety little fruit like to ripen at their own pace. Consequently, the lucky harvester spends a lot of time rummaging around a bush looking for the completely blue fruit.
