Citrus on Steroids

"Never eat anything bigger than your head." It's a good rule to live by. But recently I found this mammoth Pammelo at the store and I had to have it. Pammelos are like giant grapefruits. (The picture shows it next to my keys for scale). 

The sticker promised it to be as sweet and juicy as a ruby red. Instead the inside of mine was a bit on the dry side. Still I found it fascinating and compelling to pick at. 

I'm making my way through it in at least two sittings. Thus keeping the rule intact.
