We get them at our local farmers' market, from Pomo Tierra Ranch, and they have so much more flavor than Granny Smiths. We've found that whether you eat them raw, or bake them into a pie, the first taste is sweet, but they have a tart finish, and are so aromatic--almost floral. We've been making pie after pie out of them, almost one a week, just like this one:
If you can, get some Sierra Beauties--enough for eating, and enough for pies!
