Rambután
I've had rambután many times, and yeah, it tastes good, a little grape-like with a tropical perfume, sweeter and not as acidic as most grapes, but it is a lot of work for the amount of 'meat'. The egg-shaped fruit easily separates from the peel when you split open the covering around the equator. Then you simply plop the fruit into your mouth.
These rambutáns, however, were like nothing I've ever had before!
They are from a variety developed by Fundación Hondureña de Investigación Agrícola (FHIA - Honduras Foundation for Agricultural Investigation), the organization known world-wide for its banana development. In addition to bananas and plantains, FHIA has been instrumental in introducing, developing, and/or promoting non-traditional exportable crops for Honduras, such as rambután, cacao, sweet corn, mango, ginger, black pepper, and others. When I asked Dr. Adolfo Martínez, Director General of FHIA, why I had never had this variety before, he explained that this fruit is grown for exportation. Not fair!
According to Wikipedia, the name rambután is derived from the Indonesian word rambutan, meaning "hairy". The silly looking bad-hair-day fruit doesn't really feel hairy — the spikes feel more like little plastic appendages. In Honduras, they may also be called licha (though they are not lychees) and peluda (hairy). A common name in Costa Rica is mamón chino (Chinese sucker).
So if you ever see this odd little fruit in your local grocery store, buy it! It gets the La Gringa stamp of approval.
Sorry for the quality of the photos. The light wasn't great for photo taking and when I went to go take some new photos during the daylight, all of the rambután were gone!
