Take the puff pastry out of the refrigerator 5-10 minutes before processing. Grease 1 muffin tray (12 wells; each with approx. 90 ml content). Cut baking paper into 12 strips (approx. 4 cm wide, 12 cm long). Line each well with a strip. Unroll the puff pastry and roll it up again without baking paper. Cut into 12 snails. Press each snail flat on a floured work surface and roll out thinly in a circle (approx. 11 cm Ø). Lay out the hollows with the dough circles, press them on and chill
Wash apples, quarter and core them, cut into small cubes. Heat lemon juice, butter and 3 tbsp. sugar in a pan until the butter has melted. Add the apples and simmer for 3-4 minutes. Remove from heat, drain apples on a sieve, catch apple-butter-syrup
Cut open the vanilla pod, scrape out the pulp. Put milk and vanilla pulp in a pot and bring to the boil. Sieve the flour, add 150 g sugar and salt, mix and stir into the milk while stirring vigorously. Bring to the boil again. Remove the pot from the heat and let it cool down a little. Stir egg and egg yolks into the cream. First spread apples, then cream in the puff pastry covered hollows
Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: see manufacturer) for approx. 10 minutes. Mix the almonds with the collected apple syrup. Remove the muffin tray and spread the flaked almonds on the tartlets. Bake at the same temperature for another 10 minutes. Take them out, let them cool down briefly on a cake rack and lift them out of the tartlets using the baking paper. Dust with icing sugar
waiting time approx. 1 1/2 hours
