Cut the pineapple into slices, peel and cut out or cut out the stalk roundly. Cut the slices into pieces. Sort the raspberries, wash them if necessary and let them drip off. Beat the fat and sugar with the whisk of the hand mixer until foamy.
Add vanillin sugar and lemon peel. Stir in the eggs one by one. Mix flour and baking powder and stir in alternate portions with the milk. Pour onto a greased baking tray (37 x 32 cm) and smooth down.
Cover with pineapple and raspberries and bake in a preheated oven (electric range: 175 °C/ gas: level 2) for 30-35 minutes. Let them cool down. Heat the jam in a small pot and brush the fruits with it.
Dust with icing sugar, cut into pieces and serve. Makes about 20 pieces.
