 Preheat oven to 400 degrees. Make crust: In a food processor blend
 together flour, sugar, salt and butter until mixture resembles meal.
 Add yolk and pulse until dough begins to come together but is still
 crumbly. Press dough evenly onto bottom and up side of an 11-inch
 tart pan with a removable fluted rim. Prick bottom of crust all over
 with a fork and chill 30 minutes. Bake crust in middle of oven 20 to
 25 minutes, or until golden, and cool in pan on a rack. Make filling:
 In a small bowl sprinkle gelatin over water to soften. In a saucepan
 combine lemon juice, sugar, cinnamon, a pinch salt and 3 cups berries
 and simmer, stirring occasionally, 10 minutes. Remove pan from heat
 and stir in gelatin mixture and vanilla. Transfer blueberry mixture
 to a metal bowl set in a bowl of ice and cold water and stir until
 thickened to the consistency of raw egg white but not set, about 15
 minutes. Fold in remaining 5 cups berries and pour filling into
 crust, spreading evenly. Chill tart, covered loosely, at least 4
 hours, or until set, and up to 1 day. Serve blueberry tart with
 whipped cream. This recipe yields ?? servings.
