I was first introduced to papaya in Mexico, by Paul's mum. She taught me how to eat it by sprinkling some sugar on it, and squeezing lemon or lime juice over it. I loved it.
I still enjoy papaya, though I don't need the sprinkling of sugar anymore. We have several papaya trees growing around here, and Paul often checks them to see if there is ripe fruit ready for the picking. There is nothing like fresh papaya with a squeeze of lemon juice first thing in the morning - Yum.
