I ran into this orange, the other day. It was pink inside, like a pink grapefruit. Everything else about it proclaimed navel-orange, especially the navel and the thickness of the peel, and I’ve eaten many-a navel orange in my day, just none any color other than //orange// on the inside.

It even tasted like a navel orange, just perhaps less dry, and maybe a hint tangier. Almost a bit grapefruity, but there was absolutely nothing else grapefruity about it, other than the color of the flesh and that hint of taste which could just as well have been my imagination. What was this deliciously mutant fruit?
