Marang - Artocarpus odoratissimus
This fruit is about halfway between jackfruit and breadfruit, and a member of the same family. It grows on large trees (larger usually than jackfruit) and smells wonderful. That, of course is why someone called it 'odoratissimus'.
The skin is made of countless tiny tubules or spines, and you simply cut through it and twist it off, to reveal the individual fruit (actually arils, about the size of a grape). Each one of these has a large seed inside (which you can also eat, after boiling or roasting).
There's not a lot of taste to a marang, but it does smell good.
These are some I photographed in the Surigao City fruit market, going nicely yellow as they ripen.
Actually, there's a superb photograph at MVI~'s photostream at Flickr, which I can't compete with.
You'll also find more information at the ever-indispensable Wikipedia.
Shedney loves them; I am ordered, indeed commanded, to bring some whenever I do a bank run to Surigao City.
(There don't seem to be many exotic local fruit available here on Siargao Island. If people have a tree like this in their garden, it tends to go to the family, and no-one else).
