Being prepared for disappointment is perpetually sage advice to the young.

Lots of things don't taste as you'd expect from their names -- monkfish is the first that springs to mind. I mean, sure, they're fish-flavoured, but ...

Mangosteens (my favourite fruit) are not at all like mangoes, kiwifruit taste more like a gooseberry than a chicken, dragonfruits are pleasantly delicate but way more bland than the fiery name suggests, and so on.

If you don't like the surprise of the fruit from strawberry tree not tasting like a strawberry, then the tree tomato (tamarillo) will really annoy you. : )
