Spiked Rocky Mountain Pike's Peak Apple Crisp Recipe

5 cups tart cooking apples (I like a mix to vary flavor) peeled and sliced
1/2 tsp cinnamon
1 tsp. grated lemon rind
1 1/2 tsp grated orange rind
1 1/2 ounce Gran Marnier
1 1/2 ounce Amaretto di Saronno
3/4 cup sugar
1/4 cup brown suger (either type)
3/4 cup sifted flour
1/4 tsp. salt
1/2 cup butter
1/2 cup finely chopped walnuts (optional)

Topping: cinnamon ice cream if available, otherwise vanilla ice cream
Toss apples slices with cinnamon, lemon and orange rinds and both liquors. Place into a greased 2 qt. casserole. In a bowl mix sugars, flour, salt and butter with a pastry blender until crumbly (food processor is quicker!) Spread over apple mixture along with the walnuts, or wait until a few minutes before removing the apple crisp from oven to sprinkle on the walnuts. Bake uncovered for 1 hour or until top is lightly browned. Allow to somewhat cool before serving, but best served warm with ice cream.
