It appears to be a Papaya. I would submit a link if I could.
It is indeed a papaya. I first encountered this fruit in Brazil more than fifty years ago. The Brazilians call it a mamão, and I never learned until years later, back in the States, what Americans called it.
This is papaya or fruta bomba as it is called Cuba
Fruta bomba? I like that. It is shaped rather like a bomb, isn't it? Thanks for the comment, Sandra.
