Slab Apple Pie Print E-mail
Tuesday, 08 September 2009
Thinner than a conventional pie and twice as big, this double-crusted wonder is almost like a fruit-filled bar cookie. We started with a recipe from Cook’s Country magazine, but balked at the idea of using packaged pie dough and stumbled over the tapioca starch in the filling. Since our apples were not very tart, we spiked the filling with a tablespoon of organic apple cider vinegar.

(Makes one 12 x 16 inch rectangular pie; serves 18 to 24)

For the pastry dough:
4 cups flour, plus additional flour for rolling
10 ounces organic shortening (about 2 cups)
2 teaspoons salt
1/2 cup cold water
For the Filling:
4 pounds (about 12 medium) apples
1 cup organic sugar
1 tablespoon organic apple cider vinegar
1/2 cup cornstarch
1 tablespoon cinnamon
For the Glaze:
reserved juice from the apples, (see step 2)
2 tablespoons butter
1 1/4 cups powdered sugar

1.) To make the pastry dough: Combine the flour, shortening and salt. (If you wish to use a food processor, divide the ingredients in half and make 2 batches.) When the mixture is uniformly crumbly, sprinkle on the water and toss with your fingers to combine. Do not knead the dough or over work it. As soon as it is loosely combined, divide it into two equal pieces and roll each one out on a well-floured surface to form two 12 x 16inch rectangles. Use one sheet of pastry to line a 12 x 16-inch rimmed baking sheet, pressing the edges of the dough up the sides of the pan; put the other one on a sheet of baking parchment. Chill the pastry while you make the filling. 
2.) To prepare the apples: Peel and core the apples and slice them very thin, about 1/8-inch thick; (the slicer attachment on a food processor works well for this). In a mixing bowl, toss the apple slices with the sugar and vinegar and allow them to stand for about 20 minutes, or until they begin to release some of their juices. Holding the apple slices in the bowl, pour the residual juice into a small saucepan and save it to make the glaze.
3.) To assemble and bake the pie: Preheat the oven to 350. Toss the drained apples with the cornstarch and cinnamon and then transfer the filling to the pastry-lined pan. Top with the second rectangle of pastry and press the dough around the edges to seal. Poke steam vents into the top crust with a fork. Bake the pie until the filling is bubbling over the crust, about one hour. Cool on a wire rack for 30 minutes then top with the glaze.
4.) To make the glaze, measure the reserved juices form the drained apples, if you have more than a quarter cup, boil the juice down until it is reduced to 1/4 cup. Whisk in the butter and the powdered sugar and spread the mixture evenly over the cooled apple pie.
