Rose, I'm not sure what they are, your guess is as good as mine..when we moved in an Asian guy would always come over asking if he could have some. For a few yrs I said ok. Then I asked him if he eats them all and he said he sells them. I put an end to that real quick!!
Cub, these are no where close to be ripe and are still rather small. I have a very funny pic of a kid who didnt listen to me and tried one anyway....lol. I can't post it here tho... Got an email addy?
