Hi all,
I've got this weird fruit that I found in the Menlo Park, CA, area. I found it on some tree growing and ate some of them, people told me they were harmless (but don't know what the name is). They're fairly small, have a semi-hard spiky outside that one can bite through to get to the soft, sweet, yellow inner flesh. Any ideas? I've attached some pictures. Sorry the one with the bowl is discolored.
