Passion Fruit

I bought these based on them being labelled as Passion Fruit, though they are much larger than the fruits I am used to, small and purple, slightly sour in taste, which my Dad introduced us to when we were younger. He always suggested we put sugar on them, but I found them to be quite tasty, even with its sourness. The green one I found to be quite sour, the yellow-orange one was sweet but did not have a strong flavour. To stir the flavours, so to speak, I combined half of one with half of the other, which worked well, but still not as good as the purple variety.
