Take the puff pastry out of the refrigerator 5-10 minutes before use. Stir the ricotta, lemon juice and zest, pudding powder, sugar and egg yolk until smooth with a whisk. Unroll the puff pastry on a floured work surface and remove the baking paper
Cut the dough into 6 rectangles each (approx. 12 x 14 cm). Whip the corners of the rectangles towards the middle and press the tips slightly. Place on a baking tray lined with baking paper. Spread cream in the middle of the puff pastry pieces. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 12 minutes until golden brown, remove. Let it cool down on a cake rack
Bring jam to the boil in a pot with 1 tablespoon of water. Brush the particles with it. Put 1 teaspoon of red fruit jelly on each particle and serve
