I have purchased them like this and ripe. They are extremely difficult to peel when immature. When mature, the peeling is easier, but not easy. I made two products from the fruit, as it is too acidic to eat raw.
The first was juice. The juice had a beautiful pink colour and a good acid:sugar ratio was achieved, however, there was no real flavour or aroma and the acid still burned the tongue.
The second product was a salt ferment done anaerobically. It produced a decent pink pickle that we enjoyed eating, but the effort to peel the small fruits and the small amount one ended up eating with a meal meant that if you had this tree, most of the fruits would be wasted.
