Flourless Chocolate Torte
5 eggs, separated
12 ounces semisweet chocolate, chopped
3/4 cup butter, cubed
1/4 teaspoon cream of tartar
1/2 cup sugar
Confectioners' sugar, optional
Place egg whites in a large bowl; let stand at room temperature 30 minutes.
Preheat oven to 350°.
In top of a double boiler or a metal bowl over barely simmering water, melt chocolate and butter; stir until smooth. Remove from heat; cool slightly.
In another large bowl, beat egg yolks until thick and lemon-colored. Beat in chocolate mixture.
With clean beaters, beat egg whites and cream of tartar on medium speed until foamy.
Gradually add sugar, 1 tablespoon at a time, beating on high after each addition until sugar is dissolved. Continue beating until stiff glossy peaks form. Fold a fourth of the egg whites into
chocolate mixture, then fold in remaining whites.
Transfer to a greased 9-in. springform pan. Bake 40-45 minutes or until a toothpick inserted in center comes out with moist crumbs (do not overbake). Cool completely on a wire rack.
Loosen sides from pan with a knife. Remove rim from pan. If desired, dust with confectioners' sugar.
