I have an
apple growing in my backyard which is red-fleshed, good raw or cooked, and higher in antioxidants than white-fleshed apples (all red-fleshed apples share this distinction.)
It's an airlie red-fleshed
apple, and the variety has been around since the 1950s AFAIK.
http://www.orangepippin.com/apples/aerlies-red-fleshed Red-fleshed apples are all the rage, both for their novelty value and because they contain high amounts of anthocyanin, an antioxidant.
There are roughly a thousand varieties of apple currently in cultivation, not counting crabapples. Storage apples and fresh eating apples, cider apples and sauce apples, apples that taste like cinnamon and apples that taste like bananas. And none of them genetically modified.
A Canadian firm has been working on a GMO apple the flesh of which is slow to brown after being cut.
They
should give it up. The apple of their dreams was developed by conventional methods a century ago; It is a Ben Davis/Macintosh cross called a Cortland. Still grown in the NY area, and yummy.
I love apples; I wish I had a large orchard full of them. I'd love to grow 20 or 30 varieties that nobody has heard of, just to blow people's minds with the awesome taste experiences available from this fruit. Most folks today have no idea how diverse and wonderful this species can be, since big agra only provides a half-dozen or so varieties to the supermarket chains. Those supermarket varieties are selected not for flavor, but for appearance, longevity in storage, and durability in shipping.
