The Opal Apple is one of my favorite apples. In addition to their great taste, their natural slow oxidation rate means they don’t brown after biting into it. I was chomping on this apple at work, when things got really busy and it was left out for three hours! I learned that Opals are a non-GMO cross between a Golden Delicious and Topaz. They are grown exclusively in the United States by Broetje Orchards in Washington. They're kinda pricey, but I think it's worth picking up a couple.
