Henry's Chocolate Cake

See that frosting on top?  That's the cake batter.

Henry, a Sri Lankan man with a passion for Italian cooking, taught me how to make this. I was helping him one afternoon, and along with a delicious tuna pasta, spiced chicken, bbq ribs, florentine steak, we also made this cake.  I say "we", I was chopping onions and stirring batter all afternoon while the mosquitoes sucked me dry.  Can you believe we did all that in merely 3 hours? The florentine steak and the cake were the most popular items of the night.  My goodness it's a good cake.

It contains no flour, it's just butter, chocolate, eggs and sugar -- surely you can imagine how amazing this thing is.  It's like a rich chocolate pudding cake.

Ingredients
200g dark chocolate, broken into small pieces
150g butter, room temperature
150g sugar
6 eggs, separated

Method
Preheat the oven to 180C.  Butter and flour a cake tin.
Melt the chocolate over a double boiler.
Meanwhile, cut the butter into small cubes and beat it with the sugar with an electric whisk for a good 10 minutes at least.  The sugar has to melt.  Then beat in the egg yolks and the melted chocolate.
Whisk the egg whites with a squeeze of lemon juice and a pinch of salt.  Whisk until stiff peaks and gently fold it into the other mixture.  Pour 3/4 of the mixture into the cake tin, reserving the rest, and bake for 1 hour.  Put the leftover batter into the fridge and when the cake is done and has cooled down, frost it with the batter.
