Place the puff pastry slices next to each other and allow to thaw. Wash the lemon, grate dry and peel the peel thinly. Cut the vanilla pod in half lengthwise and scrape out the pulp with the back of a knife. Place the puff pastry slices on top of each other, roll out rectangularly (approx. 33 x 44 cm) on a floured work surface and cut into 12 squares (approx. 11 x 11 cm). Line muffin troughs with 1 paper tin and 1 puff pastry square each. Chop the chocolate into small pieces.
Boil up vanilla pulp, vanilla stick, lemon peel, milk and 250 g cream. Stir 50 g cream and cornflour until smooth and stir into the boiling cream. Simmer for about 1 minute while stirring, then remove from the heat. Melt the chocolate in the cream. Mix 2 egg yolks, eggs and sugar. Pour hot cream into the sugar-egg mixture through a sieve while stirring. Let the cream-egg-mix cool down for about 20 minutes, then fill into the muffin wells. Mix 1 egg yolk and 3 tablespoons of cream, brush the edges of the puff pastry with it. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 20 minutes. If the edges of the puff pastry become too dark, cover the muffin tray with aluminium foil. Remove the muffin tray from the oven, remove the tartlets from the trays after about 10 minutes and let them cool on a cake rack. Sort the berries, wash if necessary and dab dry.
