Its funny when you try new fruits. You don't really know how to cut it or what to eat. For example here, do you eath the white part with the seeds or the red outer part?
Welcome to the mangosteen. This fruit grows on small evergreen like trees. It is found in Malaysia, Indonesia, Thailand and a little bit in Costa Rica. The fruit is known to be difficult to grow. It was relatively expensive here when I bought it, over $3 a pound. Thus, it is clearly not available in large quantities or the price would be lower. The fresh fruit is not allowed to be imported into the United States at this time, so you will have to travel to try it.
The little brown tip at the bottom of the fruit tells how many sections are to be found inside. So now you might have figured out that it is the white part of the fruit that you eat. The largest one contains the seed. The flavor it very nice. It literally melts in your mouth when you bite into it. It is sweet, with a little bit of tangy flavor. The rind it the part that contains medicinal qualities according the the Purdue University horticultural description. The outer rind contains antioxidant phytonutrients called Xanthones. There are about 200 or so Xanthones in nature and about 43 of those are contained in the Mangosteen.
