5 cups frozen Rader Farms™ Raspberries, slightly thawed
1/4 cup sugar
2 tablespoons all-purpose flour
1 1/2 cups all-purpose flour
2 tablespoons sugar
1/4 pound (1 stick) cold unsalted butter, cut into 1/2-inch pieces
1 large egg yolk
1 teaspoon vanilla extract
sifted confectioners’ sugar
Preheat oven to 425°F. Wipe an 11-inch tart pan with a removable rim with a paper towel dipped in a flavorless oil if the surface isn’t well seasoned. Combine the flour and sugar in a food processor. With the motor running, gradually add the butter through the feed tube. Process until thoroughly incorporated. Stir the egg yolk and vanilla together in a cup. With the motor running, gradually add egg mixture through the feed tube. Pulse the mixture until it begins to pull together. If the mixture seems too dry, add 1 to 2 tablespoons ice water and process until a dough forms. The dough should be crumbly but not dry. Turn the dough directly into the tart pan. Press it up along the sides and on the bottom of the pan in a relatively even layer; the dough will have a rough surface. While the crust can be made ahead and refrigerated until ready to be baked, it tastes best when it is baked right away.
To make the filling, stir the sugar and flour together in a large bowl until blended. Add half of the Rader Farms™ raspberries and toss to coat with the sugar mixture. Spoon into the prepared crust and top with any sugar left in the bottom of the bowl. Bake for 15 minutes. Reduce the oven temperature to 350°F. Bake until the edges are golden brown and the berries are hot and bubbly, 30 to 40 minutes, running a spoon through the berry mixture to turn over any berries that still have flour on them halfway through the cooking time. Remove the pan from the oven. Carefully arrange the remaining berries, stem ends down, close together all over the surface of the tart, pressing them down gently into the hot berry mixture. Cool the tart on a wire rack. Before serving, push the tart up out of the pan. Sprinkle with the confectioners’ sugar. Cut into wedges and serve with vanilla frozen yogurt or light whipped cream!
