- 8 1/2 (1-ounce) semisweet chocolate squares
- 1/2 cup butter
- 3 eggs, separated
- 1/2 cup sugar
- 1/4 cup bourbon
- 1/4 cup flour
- 1 1/2 cups chopped pecans
Preheat oven to 325 degrees F.
Whisk egg yolks and 1/2 of the sugar in a metal mixing bowl. Place bowl over slightly simmering water, and whisk until yolks reach 140 degrees F. Remove bowl from heat and beat egg and sugar mixture with an electric mixer to a ribbon stage. Add the Bourbon to the chocolate mixture, then fold the yolk and sugar mixture into the chocolate mixture. Mix flour with pecans and fold into chocolate mixture.
Using an electric mixer, beat egg whites and the remaining sugar to form soft peaks, then fold into chocolate mixture. Pour batter into prepared pan and bake for 20 to 25 minutes. Allow cake to cool in pan and then place in the freezer for at least 2 hours. Once it's frozen, remove sides of springform pan. Invert cake onto a wire rack and remove bottom of springform pan.
Prepare ganache by bringing heavy cream to a boil and pouring cream over chocolate chips in a bowl. Whisk until completely smooth. Set wire rack with cake on top of sheetpan. Pour warm lukewarm ganache over cake, coating cake completely, recoating if necessary. Gently jiggle wire rack to help drain excess ganache. Remove cake from wire rack with spatula and place on a serving plate.
