   1      Teaspoon      vanilla extract

Preparation:

1. In a food processor bowl, mix the first 6 streusel ingredients. Add the butter and process until the mixture is crumbly; it should still have a dry look to it -- don't over process. Add the nuts then set aside. 2. Preheat oven to 180 øC . 3. Peel, core and thinly slice apples; there should be 4 cups. Place apples in the pie shell. 4. In a small bowl, mix the sugar, flour, and cinnamon. Beat the egg in a medium bowl, and add the cream and vanilla. Add the sugar mixture to the egg mixture and blend. Pour over the apples. 5. Bake for 1 hour in the lower one-third of the oven. 6. After 20 minutes, sprinkle streusel over the top and continue baking approximately 40 minutes longer, or until the top puffs and is golden brown. Difficulty : easy. Precision : measure ingredient
