1/2 cup apricot jam
1 tablespoon Kirsch
Preheat oven to 350 degrees. In a food processor, combine flour, egg, water, sugar, vanilla and butter. Process until dough forms a bowl. Cover and chill dough for 30 minutes.
Roll the dough 1/8-inch thick to fit an 8 inch fluted removable-bottomed tart pan.
Cover with parchment paper, fill the center with weights, and bake until the edges start to brown. Remove weights and paper. Brush bottom and sides with egg glaze.
Arrange pears over bottom of pie crust.
Almond pastry cream:
In a medium saucepan, bring the milk to a boil. Whip egg yolks, sugar and vanilla in a mixing bowl. Mix in cornstarch. Stir in the hot milk. Pour in a saucepan, and whisk over medium heat until thick and bubbly.
Transfer to a mixing bowl. Stir in the almond, kirsch and butter. Spoon mixture over pears and bake for 15 minutes. Cool on rack.
In a small saucepan, melt the apricot jam over low heat. Stir in the kirsch. Strain through a fine strainer and spoon over pie to glaze.
