2 cups flour
1 cup packed brown sugar
2 teaspoons cinnamon
1/2 lb. (2 sticks) butter, cold and cut into 8 pieces
5 lbs. tart apples (We recommend Granny Smith)
2 tablespoons fresh lemon juice
Preheat oven to 350 degrees. Generlously coat a 9" spring form pan with baking spray.
In a mixing bowl, combine flour, brown sugar and 1 teaspoon of cinnamon. Cut butter into the flour until pea-sized clumps form. Free 2/3 of the mixture into the bottom of the pan and 1 inch up the sides.
Peel apples and cut into thin slices. Place in bowl and toss with final 1 teaspoon of cinnamon and lemon juice. Place slices in pan, pressing down lightly. The apples will mound over the edge of the pan. Cover with remaining 1/3 crumb mixture.
Place pan on a foil-covered baking sheet and bake for 1 hour and 15 minutes, or until golden. Run knife around the edge of the pan and let cool.
