Place the lady fingers in a glass bowl so that the bottom is completely covered. Drizzle with Calvados. Peel and quarter apples and remove the core. Cut apples into pieces and steam them with 50 g sugar, cinnamon stick and 1/8 litre water for 5 minutes.
Let it cool down, take out the cinnamon stick and stir 4 tablespoons of redcurrant jelly into the compote. Put the compote on the lady fingers. Mix quark and cream and spread on the apple compote.
Decorate with the remaining currant jelly. For the almond brittle chop the almonds coarsely. Heat the remaining sugar with 2 tablespoons of water in a pan. As soon as the sugar has melted and begins to brown, add the chopped almonds and allow to caramelize while stirring.
Spread the hot mixture on a piece of aluminium foil greased with oil and let it cool down. Then break it into small pieces and decorate the trifle with them.
