The seller was clear: Blushing Golden improves with age. So I have kept my apple refrigerated for nearly a month.
Now for the moment of truth.
This is a medium-to-medium-large apple with a thin orange blush over perhaps a third of its otherwise yellow surface. It is ribbed and decorated with lenticels that take on three distinct appearances: in the blush, as darker spots of blush, and elsewhere as dark brown or, fainter, dark green spots. There are a few patches of flyspeck and one of regular russet. The fruit smells sweet and cidery.
The flesh is creamy yellow, medium coarse, juicy, and crisp, which is very pleasing for an apple that has been off the tree for so long. The flavor is lush and rich: a balanced sweet-tart, with a little lively acidity. It has something of the even sweetness of a Golden Delicious and hints of pear, honey, and banana.
This is a good late-season pick and I am pleased that I was able to buy some more on the day before Thanksgiving--the final day of the Davis Square farmers' market.
Compare Blushing Golden with Jonagold, another Jonathan - Golden Delicious cross.
