  • 20 g flour (to flour the work surface and the pan)

  • 200 ml heavy cream

Instructions

    Time: PT5M

  2. Roll out the puff pastry

    On a floured work surface, roll the pastry to about 2 mm thickness with the rolling pin, turning it regularly so it doesn’t stick.

    Time: PT10M

  3. Cut and form the circle

    In a saucepan, combine the milk, cream, 1/3 of the sugar and the split vanilla bean. Bring to a boil over medium heat.

    Time: PT5M

    Temperature: Medium

  6. Mix the eggs and sugar

    In a bowl, whisk the yolks, whole eggs, the remaining sugar and the cornstarch until a homogeneous mixture is obtained.

    Time: PT5M

  7. Temper the mixture

    Remove the vanilla bean, scrape the seeds into the hot milk, then pour the boiling milk over the egg mixture while whisking constantly.

    Time: PT3M

  8. Cook the pastry cream

    Return everything to the saucepan and cook over medium heat, stirring constantly, until the first bubbles appear, then continue for an additional 1 minute.

    Time: PT8M

    Temperature: Medium

  9. Incorporate the butter

    Remove the saucepan from the heat, add the 30 g butter in pieces and mix until fully incorporated.

    Time: PT2M

  10. Fill the pastry base

    Pour the pastry cream into the cooled puff pastry base, smoothing the surface slightly.

    Time: PT2M

  11. Bake

    Bake the flan in a preheated oven at 170 °C for about 45 minutes, watching the browning of the top.

    Time: PT45M

    Temperature: 170°C

  12. Cooling

    Remove the flan from the oven, place the pan on a rack and let cool completely before releasing the circle.

    Time: PT20M
