How serendipitous that this thread was revived now-- I just made a Valentine's pie for my husband from apples we had picked in the fall. I have made a few observations in my quest to produce the optimal pie, but from this thread, your mileage may vary substantially. Just like a good wine has a balance between acid and sweet, I like my pie apples to have a good balance. I always include 1 or 2 Granny Smiths for acid. These are softened by one or more other varietals which add fruity notes. In this last pie I used Jonagolds, one Rome, a Mutsu, and a few stray small Winesaps. IMO, very few apple varietals have the acid levels and the fruitiness to make a good pie by themselves-- Winesaps may be one of the few exceptions. As for the juice aspects, I use about 3 Tablespoons of flour for 6 or 7 apples in a 9-inch pie. I like a little juice exuding from the pie when you slice it-- maybe even a good amount. I usually get about 3 T. I've never had apples yield too much juice, but I do as one poster above suggested and prep the apples after rolling the crusts. I also find that a good pinch of salt perks up the filling immensely. My other revelation, which may be old news to all of you, is that the standard butter/shortening-flour-salt crust can be improved by adding about 1T sugar and 2 teaspoons lemon juice. The sugar helps the crust brown, thus improving the flavor. The lemon juice likely relaxes the gluten-- it may also help browning. I also made my most recent pie with King Arthur Mellow Pastry Blend Flour-- it made a dough that was easy to handle, and exceptionally tender. </musings of pie-obsessed home cook>
