Coarsely chop the hazelnuts and brown them slightly in a pan without fat while turning. Add the ground nuts and brown. Pour onto a plate and allow to cool. In the meantime, roughly chop the chocolate. Put the fat, sugar, vanilla sugar, ginger and salt in a mixing bowl and whisk until foamy. Gradually stir in the eggs.
Mix flour and baking powder and stir into the fat egg mass together with the cream. Fold in browned hazelnuts and chocolate. Grease a baking tray (32 x 38 cm). Spread the chocolate-nut dough on it. Bake in the preheated oven (electric cooker: 175 °C/ gas: level 2) for about 25 minutes. In the meantime cut the pineapple into smaller pieces. Slice the hazelnuts and pistachios in a universal kitchen machine (alternatively buy sliced hazelnuts and chop the pistachios). Place the cake on a cake rack. Mix icing sugar with lemon juice to a spreadable glaze. Spread the warm cake with it. Sprinkle pineapple, pistachio and hazelnut leaves immediately onto the still moist icing.
