Hi
@Goonergal,
Thanks for asking. I really enjoy the Sacher torte. I googled the recipe for it and then adapted it to be low carb.
I actually start by making mousse au chocolate and then adding two heaping table spoons of almond flour and carefully folding the mixture to maintain the volume. The recipe for the low-carb chocolate mousse I listed below.
Then bake it in a smallish baking tin (mine is 15cm in diameter or a bit more than 6") for about 30 minutes. It will be ready when a toothpick or skewer stuck in the middle of the cake comes out clean.
After taking the cake out of the oven, use a knife to cut around the edge of the tin. This way, the cake will not break open while it cools.
Cut the cake into three layers.
Put some low carb marmelade (I bought blackberry marmelade made with xylitol -- if you can't find it, I am sure you can make your own marmelade by just using fruit and xylitol) on top of each of the three layers and reassemble the cake).
Melt some high content chocolate at low temperature (less than 100 degrees centigrade), pour over the top, distribute evenly on top and the sides with a rubber spatula).
Put into the fridge to cool. The cake is done when the chocolate is set.
Preparation time (including the preparation of mousse au chocolate and baking time, but not the time in the fridge) is about one and a half hours to two hours.
If you decide to make it, please let me know how it works.
Mousse au Chocolate recipe
Ingredients
½ pound high cocoa content chocolate (220g)
6 ounces butter, cut in small pieces (170g)
6 large eggs, separated
½ cup xylitol or other sugar substitute
1 pinch salt
Preparation
1. Cut the chocolate into one-inch pieces and place in a saucepan. Set the saucepan into a larger one with almost boiling water. Let melt over low heat. When melted, add the butter. Blend well. Remove from the heat and let cool for a few minutes.
2. Meanwhile, place the egg yolks and the sugar in a large mixing bowl. Beat well with a wire whisk for about four minutes, until very thick and lemon-colored.
3. Add the chocolate mixture to the yolks and blend well with a rubber spatula.
4. Beat the egg whites with salt until stiff. Do not overbeat. Fold them into the chocolate mixture. Spoon the mousse into a serving bowl and chill until ready to serve.
