Ingredients:

For the frangipane:
1/3 cup sugar
2/3 cup slivered almonds, slightly toasted
6 tablespoons butter
1 eggs
1/4 teaspoon vanilla extract
1/4 teaspoon almond extract
1 1/2 tablespoons flour
1 sheet frozen puff pastry, thawed
6 fresh or canned apricot halves, pits removed
1/4 cup whole almonds, skin on
Confectioners' sugar, for garnish (which means to sprinkle over, giving an aesthetic appearance)

Cooking Recipe:

Preheat oven to 425 degrees F.
To make the frangipane, place the almonds and the sugar in a food processor and grind until sandy. Add the butter and continue mixing then add the egg, vanilla, and the flour and mix until smooth.
To make the Tart (though the word means sour, pastry tarts are usually sweet deserts) , on a floured work surface pass your rolling pin over the pastry just to flatten any ridges.
Place it on a parchment paper lined sheet pan and cut out a 9-inch disk. Spread the almond frangipane in the center of the tart leaving a 1-inch border. Firmly place the apricot halves into the frangipane spacing them evenly around the tart. Dot the spaces between the apricots with the whole almonds.
Bake until golden brown on the top and puffy, about 30 to 40 minutes. Sprinkle with powdered sugar and serve.

Ingredients:

1 1/2 cups flour
1/4 cup sugar
8 tablespoons (1 stick) unsalted butter, cut into pieces and slightly softened
1 egg yolk
Blueberry Bavarian cream, recipe follows
BLUEBERRY BAVARIAN CREAM:
4 cups blueberries
2 cups milk (not skim)
1/2 vanilla bean, split lengthwise
2 1/2 teaspoons powdered gelatin
2 tablespoons cold water
6 egg yolks
2/3 cup sugar

Cooking Recipe:

Put the flour in a large bowl. Add the sugar and mix. Make a well in the center and place the butter (comes in salted and unsalted types) and egg yolk in the well. Using your fingers, work the butter and egg yolk together until well combined, then work the butter-egg mixture into the flour-sugar mixture until combined but still loose. The dough will be crumbly, but when you squeeze a handful, it should hold together.
Sprinkle the dough into a 10-inch pie or tart pan. Press the duogh firmly and evenly onto the bottom and sides of the pan, making sure not to let the crust thicken at the corners. It should make a clean right angle where the sides meet the bottom. Chill the crust at least 30 minutes, or covered, up to 3 days. Heat the oven to 400 degrees. Bake until light golden brown, 20 to 25 minutes. Let cool before filling.
Blueberry Bavarian Cream: Pick over the blueberries, setting aside the best ones to make a circle around the edge of the finished tart. (You'll need about 1 cup.) Heat the milk and vanilla bean in a saucepan over medium heat just until it boils. Immediately turn off the heat and set aside to infuse for 10 minutes. Combine the gelatin and water in a small bowl, and let dissolve, stirring occasionally, until no dry spots remain.
Whisk the egg yolks and sugar together in a bowl. Whisking constantly, slowly pour the still-hot milk mixture into the egg yolk mixture. Return the mixture to the saucepan and cook over medium heat, stirring constantly with a wooden spoon. At 160 degrees, the mixture will give off a puff of steam. When the mixture reaches 180 degrees it will be thickened and creamy, like eggnog. If you don't have a thermometer, test it by dipping a wooden spoon into the mixture. Run your finger down the back of the spoon. If the stripe remains clear, the mixture is ready; if the edges blur, the mixture is not quite thick enough. When it is ready, quickly remove it from the heat.
Meanwhile, fill a large bowl with ice water (tap water should be fine unless the recipe calls for bottled water) half way. Strain the mixture into a medium bowl to smooth it and remove the vanilla bean. Pour off 1 cup of this mixture (Anglaise) into a large bowl and set aside. Place the medium bowl containing the remainder of the mixture in the ice water and let cool, stirring often. Add the gelatin to the cup of hot Anglaise in the large bowl and mix until completely dissolved, creating a Bavarian cream. Working quickly, fold the larger amount of berries into the Bavarian cream and spoon the mixture into the center of the tart shell. Spread until smooth and even. Before the filling cools completely, arrange the reserved berries around the edge of the tart to form a rim. Chill at least 2 hours and serve in slices, pouring a bit of the Anglaise next to each side.
