  • ½ cup unsalted butter
  • 3 tablespoons all-purpose flour
  • ¼ cup of water
  • ½ cup white sugar
  • ½ cup packed brown sugar
  • 8 Granny Smith apples – peeled, cored and thinly sliced


Preheat oven to 425°F. Melt the butter in a saucepan. Stir in flour to form a paste. Add water, white sugar, and brown sugar, and bring to a boil. Reduce temperature and let simmer. Place the bottom crust in your pan. Fill with apples, mounded slightly. Cover with a latticework crust. Gently pour the sugar and butter liquid over the crust. Pour slowly so that it does not runoff. Bake 15 minutes in the preheated oven. Reduce the temperature to 350°F. Continue baking for 35 to 45 minutes, until apples are soft.


Key Lime Pie

The best key lime pie is also the simplest, egg yolk, key lime juice, sweetened condensed milk (and maybe some whipped cream). No merengue. No gelatin. And definitely no cream cheese.
