Perhaps since it has been so many years, since my dear and I were in South America … However, passion fruit is distinctly different than dragon fruit … I remember now, you are correct, MARACUYA = PASSION FRUIT and if I do recall it is neither of these … It is a species of its own … Scientifically …
IT IS MAMEY, from the Mammea Tree, Guttiferae Family and is an ovoid Deep red fruit with a thick skin.
I HAD MAMEY in Columbia and it is used in SORBETS and malteds predominately …
Thanks for the feedback …
