Sorry, never knew of "Wani" from Bali is, even though I was raised in the neighbor island
of Java for 28 years.. But, at that time, I was not particularly paying much attention of the many varieties
/qualities that were available on mango or any other fruit for that matter.
But 2 varieties seem to stand out to me; those that being grown by Squam: Harumanis (I believe
the local name is "Gadung") my number 1 choice; and "Golek", my number 2...until a few weeks
ago when I got an opportunity to taste some NDM I bought from a Vietnamese fruit vendor (thanks to Osito
for posting their address -on another tread-);
NDM reminds me of Golek, in their shape, color, smooth; fiberless and sweetness, even the taste, but NDM
is got slightly stronger (desirable to me) mango flavor.
So, so far in my limited exposure to mango, my favorites are in this order: Harumanis, NDM then Golek.
I am growing young Golek and NDM, but still searching for Harumanis scion...
