Oooh, favourite fruit? Apples, easily. Crisp Royal Gala's in particular, but any ripe apple is good. XD
Second favourite? Easily mangoes. But bananas are very close behind. And there's a fruit which is grown in South Africa, which I can only find canned back here in Aus... But when eaten fresh over there, good lord they're tasty. I can never remember their name though...
Then Watermelons, then possibly pomegranates or lychees? Wait, no, Kiwifruit is pretty spectacular too, especially the golden ones.
Ooh, can't forget the cherries and berries. Anything with "berry" in it's name at least, yes I do know that some of them aren't even techinically berries, don't care, they're still tasty to me.
...
I'm gonna stop this list here, lest I go on to list every fruit I've ever tried.
I haven't yet eaten a fruit I've disliked (apart from ones which weren't ripe enough, or were too ripe), but I've heard that durian is particularly smelly (when cooked at least) and terrible tasting... So of course I want to at least give that a go some point. Even if it's just to finally be able to say that there is a fruit I dislike.
But yes. I'm a man of simple pleasures. Give me a nice, ripe, crisp apple, and I'm happy. At least for however long it takes me to finish it.
Here at Uni, my food bought each week is pretty limited, but you can bet that I'll at least get some apples each week if I can help it.
