It is a children’s book or folktale, I think, about a boy named Eduardo, who is sent into the desert, perhaps a trip he will not come back from or sent to his death, and he is told he can requests some items to take with him, he requests eggs and wine. He cooks the eggs, drinks the wine.  That is all I know.

Would love to learn the title of this book, and find it so that I can purchase it for my friend who is going through a difficult time and could use some comfort.
