1 cup all-purpose flour
1/3 cup powdered sugar
1/8 teaspoon salt
1/2 cup unsalted butter, chilled, cut up
1 egg yolk
1 teaspoon vanilla extract
1 (6-oz.) container plus 1 cup fresh raspberries, divided
5 oz. semisweet chocolate, coarsely chopped
1/3 cup heavy whipping cream
1. Process flour, powdered sugar and salt in food processor until combined. Add butter; pulse until mixture resembles coarse cornmeal. Add egg yolk and vanilla; pulse briefly until mixture is moist and crumbly. Shape into flat round; cover and freeze 15 minutes.
2. Break dough into 18 (scant 1-tablespoon) pieces; roll each into walnut-size ball. Press into mini muffin cups, pressing dough to top of cup. With fork, poke bottom crust three times and sides of crust several times. Freeze 15 minutes, or refrigerate 30 minutes or overnight.
3. Heat oven to 350°F. Bake 15 to 20 minutes or until golden brown around edges. (Crust will puff up during baking. If it puffs too much, poke with small knife halfway through.) Cool completely in pan on wire rack; remove from pan.
4. Meanwhile, puree 6 oz. of the raspberries (about 1 1/2 cups) in food processor until smooth. Strain through sieve to remove seeds.
5. Place 1/3 cup of the puree in medium heatproof bowl (reserve any remaining puree for another use); add chocolate. Place bowl over saucepan of barely simmering water (bowl should not touch water); heat until chocolate is melted and smooth, stirring occasionally. Remove bowl from saucepan; cool 15 minutes or until room temperature.
6. Beat cream in medium bowl at medium-high speed until soft peaks form. Whisk large spoonful of cream into chocolate mixture to lighten; fold in remaining cream. Immediately spoon into pastry bag fitted with large star or plain tip; pipe into cooled pastry cups, mounding mousse. Garnish each tart with a fresh raspberry. Store in refrigerator.
