How to make it
- Line a buttered 20 cm springform or deep tart tin with the puff pastry, pressing it up the sides, then chill it in the refrigerator while you make the custard.
- Warm the milk with the vanilla extract in a saucepan over medium heat until steaming but not boiling, then remove from the heat.
- In a bowl whisk together the eggs, egg yolks, sugar and cornstarch until smooth and pale, then slowly pour in about a third of the hot milk while whisking constantly to temper the eggs.
- Return the egg mixture to the pan with the rest of the milk and cook over medium heat, whisking continuously, until the custard thickens to a pudding consistency and bubbles gently for 1 minute.
- Pour the hot custard into the chilled pastry case and smooth the top, tapping the tin to release any air bubbles.
- Bake in an oven preheated to 200C (400F) for 35 to 45 minutes until the top is deeply golden-brown and just set with a slight wobble.
- Let the flan cool completely to room temperature, then chill for at least 4 hours or overnight before slicing so the custard sets firmly.
