And speaking of watercore,  this year I have noticed (for the first time) a
few apples (of different varieties) displaying the supersaturated appearance
of watercore but just under the skin (and sometimes a bit deeper) but not in
(or even near) the core itself.
Examining the exterior of the fruit (the skin that covers these areas) does
not indicate any abnormality within, i.e. the fruit must be cut or bitten into
before the watery areas can be seen.  Anyone know what I'm looking at?  Is it
just a derivation of typical watercore?  Common elsewhere?  

Many thanks,
