In my right hand, I'm holding a pomelo. And in my left hand, I'm holding a pomelo the size of my head! We got these from my aunt's place in town, and walking under the tree I'm surprised people don't usually duck for cover with these fruit hanging overhead. Quite an amazing fruit this, with a milder-than-grapefruit flavor. They seem to be seedless, which prompts the obvious question, "How does it grow?" Well, beats me. And if you came to this site for botanical reference, you came to the wrong place. Sorry.
Speaking of reference, the Wikipedia site (http://en.wikipedia.org/wiki/Pomelo) does a good job of providing an ample amount of information on the pomelo, a.k.a. Citrus Maxima or Citrus Grandis, and a detailed series of pictures, very much in a manner that I strive to emulate. The reason for my Walk-Like-An-Egyptian pose? I was trying to hold up the fruit so you could see which was bigger, the pomelo or my head. ;-)
