In Java they also believe that they will be constipated from salak if they don't eat the white skin on the fruit.
Salak picked too late loses its crisp texture and becomes like an old mealy apple. I don't enjoy them at this stage. I don't know which Bali Salak I tried, (it was in Bali, so only assuming it was Bali Salak) but it was good. Not as good as Salak Pondoh, which has no astringency and thick flesh.
My big Salacca mission right now is to encourage people to try Salacca affinis. The flesh is thin, but what flesh there is is perfect, atleast to my taste. I am just as excited to grow S. affinis as I am Salak Pondoh.
