1-1/2 cups flour
1/2 teaspoon salt
3 tablespoons cold butter
3 tablespoons vegetable shortening
Combine flour and salt in a mixing bowl. Cut in the butter and shortening with a pastry blender or a fork. Add about 5 tablespoons of cold water until you can form the dough into a ball. Roll it out to fit a 9-inch deep-dish pie plate.
2-1/2 cups chopped walnuts
1 cup dark maple syrup
5 eggs
2 teaspoons lemon juice
1/4 teaspoon cinnamon
5 tablespoons melted butter
1/2 teaspoon vanilla
1/2 teaspoon salt
Heat oven to 375 degrees F. Spread the walnuts in the unbaked pie shell. In a mixing bowl combine all remaining ingredients and blend with a whisk until smooth. Pour the filling over the walnuts. Bake for 35 to 40 minutes, until firm.
