Knead the dough slightly just until it comes together then wrap it in plastic wrap and place in the fridge for 1 hour.
After 1 hour, remove it from the fridge and place it on a floured working surface.
Roll it into a thin sheet, about 2mm thickness, then cut it and mold it into small tartlettes rings or pans.
Bake the crusts in the preheated oven at 350°F - 180°C for 12 minutes or until just slightly golden brown on the edges.
Allow to cool down in the pan.
Strawberry Compote:
Combine the strawberry puree, lemon juice and half of the sugar in a saucepan.
Mix the remaining sugar and pectin in a bowl.
Once the puree begins to boil, start adding the pectin mixture, little by little, mixing well while cooking.
Once you finished adding the pectin, continue cooking for 2 more minutes then remove from heat, cover with plastic wrap and place in the fridge to cool down.
Frangipane:
Mix the butter and sugar in a bowl for 2 minutes until creamy and pale.
Add the egg yolks and vanilla and give it a good mix.
Stir in the almond flour and flour and mix to combine then stir in the pastry cream and mix well.
Spoon the frangipane into pastry bags fitted with a small round nozzle.
To finish the tartlettes:
Spoon 1-2 teaspoons of strawberry compote at the bottom of each crust.
Pipe a layer of frangipane on top and cover with slices of almonds.
Bake in the preheated oven at 335°F - 170°C for another 15 minutes or until the frangipane looks golden brown.
Allow the tartlettes to cool down in the pan before serving.
