Chocolate cake

Again a recipe from my sister (well, actually one of her cookbooks).

125g butter
6 egg yolks
150g sugar
125g dark chocolate
6 egg whites
250g ground almonds
50g flour
1 teaspoon baking soda

beat egg whites until a foamy mass forms. Mix everything in the indicated order and put in form. Bake 45-55 min at 180ºC (400F).

Chocolate icing

120g dark chocolate
3 teaspoons water
30g butter
2-3 teaspoons sugar

combine chocolate and water and let melt in a waterbath. Add butter and let melt. Add sugar and immediately cover the cake using the back of a spoon.
