Chocolate, Pear, and Pistachio Tart

Preheat oven to 450 degrees F. In a medium bowl stir together flour, sugar and salt. Using a pastry blender, cut in butter until mixture resembles fine crumbs. Add sour cream and oil; toss with a fork to combine. Gradually sprinkle with enough of the ice water to moisten, tossing gently. Gather pastry into a ball, kneading gently just until it holds together (pastry may appear crumbly). Form into a rectangle. Wrap in plastic wrap and chill 1 hour.

Roll pastry between two sheets of waxed paper into a 16x7-inch rectangle, lightly flouring pastry as needed to roll easily. Transfer to a 14x4 1/2-inch tart pan with a removable bottom. Press pastry into fluted side and trim edge. Prick bottom of pastry with a fork. Line pastry with a double thickness of foil. Bake 8 minutes; remove foil. Bake 6 to 8 minutes more or until dry and golden. Cool on a wire rack.

In a small bowl combine whipped topping and chocolate. Microwave 30 to 45 seconds or until melted and smooth, stirring once or twice. Spread in tart shell; let stand 15 minutes.

Slice pear and toss with lemon juice. Arrange pear slices on chocolate mixture. Drizzle with honey and sprinkle with pistachios. Chill 1 hour or until chocolate mixture is set.
