I cut open the Golek today, here's my personal observation:
fiberless, creamy textured, not too sweet with just a slight hint of sourness, hardly has any typical mango aroma; sorry no brix report. (don't have the tool).
This fruit ripened super fast; when I found it yesterday, it was still rather firm, but today it became so surprisingly soft. My wife's comment was: "similar to a good Manila mango from the market".
So, needless to say, this very first and only fruit from my young tree didn't impressed me. Not sure if this is the same exact variety that I used to know, as to my recollection this variety is one of the high demand mangos in Java, where fruits are bigger, firmer and smoother. Or. could it be that the future crops will get better? If not getting any better, I won't be despair, now that I understand that I can always try to do the top-working...
