Our pomelo's rind was yellowy-greenish. The inner part of the rind was not what I expected. I'm used to the whitish-yellow that accompanies most citrus fruits, but the pomelo's is whitish-pink. The rind is very thick. I would say at its thinnest it was 1cm and thickest 1.5cm. It was so thick that it wouldn't come off all at once. When you peel off all the skin, there is still a substantial part of the pinky-white rind interior to go before you get at the actual fruit sections. It looks a little funny at this point. There are bumps on the white stuff that make it look an awful lot like chicken skin.
Once you peel off the tricky, multi-layered rind you get to the good stuff. The skin on each individual piece of pomelo is quite thick. I just peeled it off as well and just ate the little, juice pouches. So, after nearly 10 minutes we get to the point where we can actually try the thing. A pomelo tastes like a mild grapefruit. Imagine a grapefruit without all the bitterness and that's nearly a what a pomelo tastes like. It has a slight aftertaste that can only be described as Chinese, but that's understandable from a fruit from South East Asia. I enjoy the taste very much.
The pomelo we had had very small seeds. I don't think any were bigger than the head of a pin, but I think that it was just a very good time in its development to eat it. I imagine when fully developed the seeds would be just plain massive, like the fruit itself.
One note of caution when peeling and eating a pomelo. It is a citrus fruit, so be wary of squirting. Be wary of squirting on a scale you've never experienced before. A pomelo is at least three times bigger than an orange, but its squirting capability is probably 3 squared. I consider myself lucky, since my glasses shielded my eyes from any stray liquid jetting across the kitchen. An orange will make your fingertips messy, while a pomelo will have your hands messy and sticky down to the wrists.
A pomelo is like a big, mild, difficult grapefruit and definitely makes you work hard for the pleasure of eating it. To get the most of the experience I would say you should definitely give your self a solid 20 minutes. Also, do it with someone. It makes the peeling easier if you do it in shifts and a pomelo is a lot of fruit for the eating (even with its massive rind).
VERDICT: Make, the entire production involved prevents it from being a favourite, but the great taste can't be ignored.
