I got this AMAZING recipe from the Joy of Cooking cookbook. It is easily the most delcious thing that I have ever had the pleasure of tasting or baking. Go ahead, give it a try....if you dare!
You'll need:
1 lb. semisweet chocolate
10 tbsp. unslated butter cut into 10 pieces.
5 large eggs with yolks and whites separated
1/4 tsp. cream of tartar
1 tbsp. sugar
boiling water
large baking dish
8 x 2'' cake pan
parchment paper
crisco
Grease a 8 x 2 inch cake pan and cut out parchment paper and place it at the bottom of the dish.
Preheat oven to 325 degrees F.
Combine chocolate and butter in a heatproof bowl and set it in the microwave. Microwave at intervals of 30 seconds until the mixture is smooth and melted.
Wisk in the egg yolks until combined.
Beat in a medium bowl the egg whites and cream of tartar until soft peaks form and then slowly add the sugar until peaks are stiff but not dry.
Fold in 1/4 of the egg whites into the chocolate mixture to temper and then fold in the rest.
Scrape the mixture into the cake pan and set inside a large baking dish. Fill it with boiling water until it reaches 1/2 way up the cake pan and CAREFULLY place in oven.
Bake EXACTLY 30 minutes. Take out of baking dish and let cool completely on a wire rack. Place in the fridge until chilled. Take a knife and run around the pan and invert on a plate or serving dish. Sprinkle with powdered sugar if desired.
Note: Inside will be gooey and you may think that it's under cooked but it's just the nature of the dessert.
Enjoy!!
