Hi Ozzie, I don't know what it is called but I think I saw the same thing you are 
describing in Honeycrisp grown last year in Massachusetts. The grower called it 
watercore, so I took his word for it, but this was in early September, so I didn't 
think temps had been right for watercore to develop. Then this year I saw it in a 
few different varieties growing in low spots. I guess I just assumed I had missed 
optimum picking time, but I think now I was making an incorrect assumption. Maybe 
we could email Renae and ask her...
a little rain,
