Don't fret if you 're a papaya newbie (I was too!). Just head over to
this website for all the information you need (though their picture looks nothing like the papaya I bought... mine was much longer and still a little bit green, but the key is that is had speckled on the outside and was a bit soft - not mushy, though - to the touch). It was far easier cutting/peeling/de-seeding than I thought. If it's at the optimal ripeness, then it will be very juicy, so make sure to have a good amount of work space (and paper towels!). The de-seeding could be messy too, but not if you use a large spoon and hold it over the trash (seed side down) when doing it.
