Place the puff pastry slices next to each other and let them thaw at room temperature for about 10 minutes. In the meantime whisk the egg yolk and 1 tablespoon of cream. Then cut in half and place on two baking trays lined with baking paper. Brush with egg yolk and bake one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 12 minutes. Remove from the oven and let cool on a cake rack.
In the meantime chop the almonds. Crumble the meringue. Whip 500 g cream until stiff and allow vanilla sugar to trickle in. Mix in the chocolate flakes and almonds. Cut open puff pastry strips. Put 2 tablespoons of meringue crumbs aside for decoration. Fold the remaining meringue into the cream. Spread the meringue on the puff pastry bases with a tablespoon. Place the lid on top and press down lightly.
