Do berries count as "fruit"?
My favourites are European blueberries — Vaccinium myrtillus. (What heathens and infidels call "bilberries")
Nobody has yet found a way to cultivate them successfully, but they do grow wild and are more or less abundant where I live for at least a month in summer.
I find them best raw. I like to eat them in milk without any sugar. Also good frozen and thawed, but like every fruit then they are more mushy and don't taste fresh.
They are smaller, and have more colourful, tastier and nutritious flesh than the cultivated American blueberry.
The European variety was of course called "Blueberry" first. The American variety was named "Blueberry" because it resembles its European cousin.
I think it should be illegal to market American blueberries as "Blueberries" in Europe, which is something I do see happen too often because of the name confusion caused by American influence. It should also be illegal to add American blueberry flavour to blueberry products — because that tastes nothing like the real thing.
BTW. A close relative to the European variety does actually grow wild in parts of North America, but not many people know about it. I assume that because it can't be cultivated, it is very rarely seen for sale, especially outside the far north.
