Flourless chocolate orange cake is a very yammy cake that Anna Olson was preparing on her tv show, "Sugar". I saw the show and i said i have to have that cake. Fortunately, i found the recipe on Food network.
So, here it is:
8 ounces bittersweet chocolate chopped (bittersweet only)
2 tablespoons unsalted butter (i used about 5 tbs)
5 large eggs at room temperature, separated
1 teaspoon finely grated orange zest (i used the zest of one orange)
1 cup ground almonds (i used walnuts)
3/4 cup + 2 tbsp superfine sugar (i used regular sugar)
2 tablespoons orange liqueur
1 teaspoon apple cider vinegar (i used a few drops of lemon juice)
icing sugar and/or cocoa powder for dusting
Preheat oven to 350 degrees F. and grease a 10-inch springform pan. Melt chocolate and butter over a pot of barely simmering water until smooth.
Stir in egg yolks gently, one at a time, then fold in orange zest and ground almonds.
Whip egg whites until foamy,
then add sugar while whipping until whites hold a medium peak.
Fold whites into chocolate mixture in 2 additions and gently fold in orange liqueur and vinegar (the vinegar keeps the cake from cracking too much as it rises).
Pour batter into prepared pan
and bake for 35 to 45 minutes, until a tester inserted in the center of the cake comes out clean.
Let cake cool completely in pan. Remove cake from pan and dust with icing sugar and/or cocoa powder.
