Oscar,
I have several pitangatubas, and all of them are fruiting now. They are from different sources of seeds. They look a bit different to one another as far as hight, leaf size, and so on. They all taste tart/acidic to me (sabor azedo e acido).
I prefer to eat sweet fruits out of hand. I like the tart/acidic ones to make juices, jellies, and ice creams.
For example, a nice ripe white sapote or a nice ripe sapoti I eat out of hand.
Maracuja amarelo (yellow passion fruit), araca-boi, or pitangatuba - I prefer to process them.
