To make the pastry, put the flour, butter, sugar, and salt in a food
processor, and process until the mixture ressembles breadcrumbs. In a small bowl or measuring cup, mix together the egg yolk, with the vanilla and water. With the machine running, pour in this mixture and process until the dough just comes together. Press the dough into the bottom and up the sides of a 10 inch springform pan and chill until needed.
Meanwhile, peel, halve, and core the pears. Spread the breadcrumbs over the bottom of the prepared tart shell, and arrange the pears all over the bottom with the rounded side out. You may need to cut some of the pears to fit in the shell
To make the filling, put the sugar, butter, almonds, whole egg,
flour in the food processor and process until smooth. Cover the
pears with the almond mixture. Bake in a preheated 375 degree oven until golden brown, approx. 1 hour. Let rest for an hour before serving (This torte will keep in the fridge for a week). Serve with lightly sweetened whipped cream mixed with mascarpone
