CINNAMON RAISIN APPLE KUCHEN

Steps:

• Position rack in center of oven and preheat to 375.
• Butter a 9-inch tart pan with 1 1/2 inch high sides and removeable bottom. (I use a springform pan) Set aside.
• For crust:.
• Blend flour, butter, sour cream, 1 T sugar, hard-boiled egg yolk, cinnamon, nutmeg and salt, till mixture resembles coarse meal.
• Transfer all but 1/2 cup of mixture to prepared pan.
• Press mixture evenly into the bottom and up the sides of the pan.
• Bake 10 minutes. Brush with egg white.
• Continue baking till brown, about 15 minutes.
• Transfer to rack.
• Reduce oven temp to 350.
• Add remaining 2 T of sugar to reserved mixture in bowl and blend. Chill crumb mixture till ready to use.
• For Filling:.
• Thinly slice apples.
• Mix sugar, sour cream, egg yolks, flour, vanilla and cinnamon till smooth (referred to in later steps as "custard").
• Arrange half the apple slices, overlapping slightly, in concentric circles on prepared crust.
• Sprinkle half the raisins or currants over.
• Repeat procedure with remaining apple slices and raisins.
• Spoon custard mixture over apples, lifting apples slightly and smoothing custard between slices.
• Sprinkle reserved crumb mixture over top.
• Place pan on cookie sheet. Bake till custard is set, covering edges of crust with foil if browning too quickly, about 65 minutes.
• Let stand 10 minutes. Remove sides of pan. Serve warm or at room temperature with whipped cream or cream fraiche. Or just as is :).
