Not tangential at all. Actually directly answers the question, above. Had you not posted it, I likely would have.

From the article:

They’re classified as a sweet onion, and because of their mild flavor (they don’t make your eyes tear up), some folks can eat them like an apple. Most of my customers do.

I grew up hearing stories of the long lost Amelia Bedilia onion that you’d eat like an apple. As the story goes that variety was lost.
