Separate the eggs for the sponge roll. Beat the egg whites until stiff, adding 75 g sugar and 1 pinch of salt. Fold in the egg yolks one by one. Sift flour and baking powder over it and fold in carefully.
Spread the mixture on a baking tray (35 x 40 cm) lined with baking paper. Bake in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for approx. 10 minutes. Turn the plate over immediately on a tea towel sprinkled with a little sugar.
Pull off the paper. Stir the jam until smooth and spread it on the sponge cake except for a little bit. Roll up from the long side. Let it cool down.
For the compote, drain the cherries and collect the juice. Boil up the juice and vanilla sugar. Mix starch and 8 tbsp. amaretto until smooth and thicken the juice. Bring to the boil while stirring and simmer for about 1 minute.
Pour into a large wide dessert bowl (approx. 26 cm Ø) and allow to cool.
For the chocolate cream, heat 250 g cream. Break the chocolate into pieces and melt in it. Stir until smooth and put aside about 3 tbsp. for decoration. Let the rest cool down a little, spread on the cherries.
Chill for about 1 hour. Cut off approx. 9 slices from the sponge roll (use the rest for other purposes) and sprinkle with the rest of the Amaretto. Place on the rim of the bowl.
For the cream, stir curd cheese and mascarpone until smooth. Mix cream firmer and sugar and stir in. Whip 250 g cream until stiff, fold in. Distribute in the bowl. Chill for at least 2 hours. Warm up the rest of the chocolate cream.
Drizzle the rest of the jam over the cream.
