For the shortcrust pastry, put flour, 125 g sugar, salt, 1 packet of vanillin sugar, egg yolk, 1 tablespoon cold water and butter in flakes in a mixing bowl. Knead first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Form into a roll and cut into 8 slices. Roll out each slice of dough to a circle (approx. 13 cm Ø) on a floured work surface. Place each slice in a greased, flour-spread tartlet mould (10 cm Ø, with lift-off base). Slightly press down the rim and base. Prick the base several times with a fork. Chill for about 40 minutes.
Then bake in the preheated oven (electric oven: 200 °C/ convection oven: 175 °C/ gas: level 3) for 18-20 minutes on the bottom rack. Remove from the oven, place on a cake rack and allow to cool for about 20 minutes. Remove the tartlets from the ramekins and let them cool on a cake rack. In the meantime, roughly chop the chocolate. Heat the cream in a pot, add the chocolate and dissolve it while stirring. Chill for about 1 hour until the chocolate cream begins to set.
In the meantime, wash, peel and quarter the pears and cut out the core. Cut quarters into slices. Bring lemon juice, 2 tablespoons sugar, 1 packet vanilla sugar and 750 ml water to the boil in a saucepan, add pear wedges, bring to the boil again briefly and cook over a low heat for 2-3 minutes. Carefully lift out and drain very well on kitchen paper. Wash the grapes, pluck from the panicles, drain very well
Stir the chocolate cream briefly and fill into the tartelets with a tablespoon. Spread the fruit on top and press down gently. Chill the tartelettes for another 45 minutes. Dust with icing sugar and decorate with lemon balm leaves
waiting time approx. 2 1/2 hours
