Roll the pastry out on a lightly floured work surface into a 1-2 mm thick round. Cut out pastry circles slightly larger than the size of the cavities of your tartlet tray, using as a cut out a suitably sized bowl placed up side down on the pastry. Press the trimming together into a ball and roll it out again for more cut outs.

Butter the cavities of the tray (this step is not needed if using a silicon tray) and place the pastry circles inside each cavity. Pierce holes into the pastry with the help of small fork and bake for about 10-12 minutes, until the pastry is lightly browned. Take out of the oven and let cool.

Place the cream and mascarpone in the freezer 15 minutes before using. Very cold cream is a key to a successful Chantilly - check out my tips here, which also apply for this mascarpone version. Mix both creams together into a bowl and whisk until the cream starts to thicken. Add the vanilla extract and sugar in small batches and stop as soon as the whisk leaves defined marks into the cream.

Unmould the pastry shells and fill them with whipped cream. Cover them with berries and reserve on a serving tray. Store in the fridge until time of serving.

Pierre Hermés shortcrust pastry recipe (2 hours before using)

Crack the egg into a small bowl; slice open the half vanilla pod and scrape the beans into a teaspoon. Reserve.

Chop the butter into small chunks, toss them into a large mixing bow and beat them with a spatula to soften. Add in succession the icing sugar, almonds, salt, vanilla beans, egg and flour, stirring well after adding each ingredient.

Shape the dough into a ball with your hands, wrap it in cling film and chill for 2 hours in the fridge before using.
