Finally. Sorry for the delay. Here is a KP-friendly recipe for sacher torte. We make it this way all year round.
Melt together in the microwave (for about 4 minutes):
16 dkg ground walnuts
16 dkg sugar
10 dkg dark chocolate
2 dl water
After it's cool, add six egg yolks. Whip the six egg whites separately with a bit of sugar. Once whipped add two tablespoons breadcrumbs/matzoh meal then add to the other mix.
Bake for 45 minutes on 180 C.
Once cool add a layer of preserves (raspberry or apricot) and the chocolate icing on top:
15 TBSP sugar
5 dkg butter or margarine
4 TBSP water
3 TBSP cocoa powder
Melt together and once solidified spread onto the cake. Cover with plastic wrap held up by toothpicks.
