My neighbor has what I'm pretty sure is a Peruvian apple cactus. Here's a fruit from it:
The fruit got overripe and split while it was still on the cactus.
Is it still edible, since it never touched the ground? Do I just scrape away that part? Can the fruit be eaten just like a dragonfruit—separate the pulp from the peel and you're good to go? Or is it more like a prickly pear that has tons of inedible seeds in it?
