Apple Tart With Eggnog Creme Anglaise

• Pastry:
• 10 tablespoons unsalted butter, slightly softened
• 1/3 cup sugar
• 1 egg, lightly beaten
• 2 cups flour
• 1/4 tsp salt
• Creme anglaise:
• 3 egg yolks
• 2 tablespoons sugar
• 1 cup milk
• 1/2 tsp nutmeg
• 1/4 teaspoon cinnamon
• 3 tablespoons dark rum
• Filling:
• 1 1/4 cups sour cream
• 1/4 cup granulated sugar
• 1 cup flour;divided
• 2 eggs
• 1/2 teaspoon cinnamon
• 1/4 teaspoon nutmeg
• 1/4 teaspoon salt
• 4 medium granny smith apples
• 1/2 dark-brown sugar
• 2 ounces walnuts, coarsely chopped
• 3 tablespoons unsalted butter, softened

1. To prepare pastry: Cream together butter and sugar until light and fluffy. Gradually whisk in egg. Combine flour and salt; slowly add to butter mixture, mixing well. Cover with wax paper and let rest 30 minutes. Press onto the bottom and up the sides of a 9 1/2 inch quiche pan or deep-dish pie pan. Set aside. (This can be done 48 hours in advance, covered and held in refrigeration).
2. To prepare the creme anglaise: Whisk together the egg yolks and sugar. In a medium saucepan, bring the milk to a boil. Whisk into the yolk mixture and pour back into the pan. Stir constantly over medium heat until the sauce thickens. Remove from the heat and stir in the nutmeg and cinnamon. Let the sauce cool 15 minutes before stirring in the rum. Cover and refrigerate until ready to use. (This can be done 48 hours in advance).
3. Prepare the filling: Whisk together the sour cream, sugar, 1/2 cup flour, the eggs, cinnamon, nutmeg and salt. Peel, core and cut the apples into 1/4-=inch slices; cut the slices in half crosswise. Stir into the sour-cream mixture.
4. Transfer the apples to the pastry-lined pan and bake in a preheated 350 degree oven for 20 minutes. While the tart is cooking, combine the remaining 1/2 cup flour, the brown sugar and walnuts. Add the butter to form a crumb mixture. Remove the tart from the oven, sprinkle the crumb topping and continue baking 25 minutes.
5. Cool the tart on a wire rack. Serve warm or at room temperature with the chilled creme anglaise.
