sorry about the long delay - I had several medical appointments and then the heating failed (naturally during the weekend where you can't get someone to repair it)and it was too cold in my study to sit at the computer.
But here it finally comes: the authentic Blackforest cake recipe.
For the dough you need
either 3 thin chocolate sponge cakes or
- 125 g / 4.5 oz soft butter
- 125 g / 4.5 oz sugar
- 6 eggs
- a vanilla pod
- 125 g / 4.5 oz finely grated chocolate
- 125 g / 4.5 oz finely grated almonds
- 125 g / 4.5 oz flour
- 2 teaspoons of baking powder
Separate egg yolks from egg whites and beat the whites together with 2 tablespoons of sugar to a stiff meringue mass.
Scrap out the seeds from the vanilla pod. (Store the empty pod in a jar of sugar to make vanilla sugar which you can use in cookies etc.)
Whisk the butter till it is fluffy and then add the egg yolks, the rest of the sugar and the vanilla seeds. Whisk thoroughly and then gradually add the flour, almonds, chocolate and baking powder.
Fold in the meringue mass.
Butter a spring form (about 25 cm / 10 inches diameter) and dust it with flour. Fill in the dough and bake at 170-180°C / 340-355°F for 45 to 60 minutes.
Leave the cake to cool for a few minutes, then remove it from the form and put it on a rack until it is completely cold.
Only then cut it into 3 layers, horizontally (either use a very sharp thin-bladed knife or a solid sewing thread for cutting).
The filling:
- 3/4 l / 3.1 cups of cream
- 6 leaves of gelatin or 3 slightly heaped teaspoons of ground gelatin
- 75-100 g / 2.6-3.5 oz of icing sugar (powdered sugar)
- a dollop of cherry brandy (leave that away if you intend the cake for children)
- Either 2 jars of cherries or amarelles (sour cherries) or 750 g / 1 lb 10.5 oz of cherries or amarelles and 1-2 tbsp sugar
Stone the cherries, sugar them and leave them to infuse a little. Bring them to a boil and then drain them thoroughly and leave them to cool off. Keep the juice - you'll need it later.
Alternatively, use drained jarred cherries or amarelles.
Soak and liquidify the gelatine according to instructions on the package. Leave it to cool till it is just tepid.
Whip the cream till it is very stiff, gradually adding powdered sugar to taste, and add the gelatine. Mix it thoroughly, else there will be rubber-like gelatine lumps. (If you intend to eat the cake immediately, you can leave the gelatin away.)
Divide the cream up: 2/3 for the filling, 1/3 for icing.
If you like, mix the cream for the filling with a dollop of cherry brandy.
Assembling the cake:
Drizzle the bottom slice of sponge cake with cherry brandy or some of the cherry juice. Spread it with a little cream and a layer of cherries. Top with cream and put on the next layer of sponge cake. Repeat procedure with the 2nd slice of sponge cake.
Put on the third layer of sponge cake, cover the top and the sides of the cake with the cream you left for icing. Decorate with cream and cherries (if there are any left). Dust with cocoa or grated chocolate.
