Anyone?

My neighbor brought these over for me to taste.  Honestly, if they would not have had stems on them I would have thought they were larvae of some kind.  I thought the flavor was kind of odd and I think it's because there is a hint of vanilla plus there doesn't seem to be any acidity. The brown ones are sweeter just like a raisin is sweeter than a grape.

That's a saucer and the biggest berry is an inch long.
