This large yellow apple looks and smells like a Golden Delicious.
It's perhaps a little more squat, and the blush, when there is one, is different, a streaky orange pink with a hint of copper.
(Golden Delicious will blush if you let her, but the effect is more solid, like this.)
The green lenticels are a little different as well.
But the classic conical shape, the moderate ribbing, and the rich cider-and-honey aroma all suggest Golden D, in the family tree if not in the flesh.
It has an open calyx and is quite firm.
New York's yellow flesh is crisp and hard, halfway between coarse and fine-grained, and pleasingly juicy.
The flavors are well balanced, perhaps a little sharper than those of Golden Delicious but with plenty of honeyed sweetness.
The biggest tell, for me, is the prominent banana note front and center.
This flavor pops up in apples from time to time but I can't think of another variety where it is as obvious. Certainly not Golden Delicious, which presents a different set of tastes.
I'm not shy of hard apples and find New York good and fun to eat.
NY 315 is clearly a product of the breeders at Cornell, but it must still be under evaluation because I can't learn any information about its parentage online.
