Ciao Italia: My Lifelong Food Adventures in Italy
4 eggs, separated
200 grams sugar (7 ounces)
200 grams unsweetened chocolate in fine pieces (7 ounces)
150 grams of butter (5 1/2 ounces unsalted butter)
Grease a 9-inch square baking pan and line it with greased parchment paper.
Melt the butter with the sugar until liquefied. While it is still hot, add in the chopped chocolate and stir until it is melted.
Beat the sugar and egg yolks well.
Separately beat the egg whites then fold them into the chocolate and egg mixture.
Pour into the prepared pan and place into cold oven. Turn temperature to 350F.
Bake for about 20 minutes. Cake should rise then fall, resembling a flat brownie.
Cool well then refrigerate, dust with powdered sugar, cut into pieces.
