I'm a big fan of grapes which I think are underrated, but my favorite would have to be oranges because not only are they very refreshing, they also make a great artificial flavor as opposed to artificial watermelon (ew) and artificial strawberry (yuck). Second place is probably blackberries for me.
Now I’m not a picky person at all, except when it comes to fruit. I don’t enjoy fruits like peaches or oranges unless they’re cut up because they make a mess and they’re too juicy for me. Because of that, my favourite fruits are grapes (the green hard ones) and bananas!
