1. Make the crust: Preheat the oven to 350°. In a medium bowl, fold together the crushed gingersnaps, melted butter and sugar. Press the mixture into a 10-inch pie pan until flat and even. Place in the oven and bake for 15 minutes, until the edges start to set, then remove from the oven and set aside to cool completely.

2. Make the filling: Thinly slice the apples. Place them in a large bowl and drizzle the lemon juice over the slices. In a small bowl, combine the cinnamon, cloves, nutmeg, sugar and 2 tablespoons flour. Fold the mixture into the apples until the apples are just coated. Spoon the apples into the reserved crust.

3. Make the topping and bake the pie: Increase the oven temperature to 375°. In a medium skillet set over medium-high heat, fry the bacon until crisp, about 7 to 10 minutes. Drain the slices on paper towels and set aside to cool. In a medium bowl, combine the flour and brown sugar. Using your fingers or a pastry cutter, mix the butter into the flour and sugar mixture until pea-size clumps form. Crumble the cooled bacon and add it to the flour mixture. Sprinkle the streusel evenly over the top of the apple filling and place the pie in the oven. Bake until the top is browned and the apples are tender, about 45 minutes. Serve warm or at room temperature.
