Garash Cake

Steps

1. 1
   Heat the oven to 170°C. Draw four 22 cm circles on baking paper.
2. 2
   Whip the egg whites to soft peaks, then add the caster sugar a spoonful at a time until stiff and glossy.
3. 3
   Fold in the ground walnuts in three additions, keeping as much air as possible — there is no flour to save you.
4. 4
   Spread the mixture over the four circles and bake 15 minutes. Cool completely on the paper.
5. 5
   For the cream, melt 200 g of the chocolate and cool it. Beat the butter with the icing sugar, then beat in the yolks one at a time, then the cooled chocolate.
6. 6
   Stack the layers with the buttercream between them, finishing with a thin coat over the top and sides. Chill 1 hour.
7. 7
   Heat the cream, pour it over the remaining 100 g chocolate, stir smooth, and glaze the chilled cake. Set in the fridge before slicing with a hot knife.
