Ingredients:
- 1 sheet (17 oz / 480g) frozen puff pastry, thawed
- 1 large (50g) egg, beaten
- 1 cup (240ml) whole milk
- 1 vanilla bean (3g), split and scraped
- 1/3 cup (65g) granulated sugar
- 2 tbsp (16g) cornstarch
- 3 large egg yolks (55g)
- 2 tbsp (28g) unsalted butter, room temperature
- 1 lb (450g) fresh purple or red plums, pitted and sliced into 1/3-inch wedges
- 2 tbsp (30g) apricot jam
- 1 tsp (5ml) lemon juice
Instructions:
- In a medium saucepan, combine milk and vanilla bean seeds. Heat over medium until simmering.
- In a separate bowl, whisk egg yolks, sugar, and cornstarch until pale.
- Slowly pour half of the hot milk into the egg mixture, whisking constantly to avoid curdling.
- Return the entire mixture to the pan and whisk over medium heat until it thickens into a velvety cream.
- Remove from heat and stir in the butter until melted and glossy.
- Roll out the puff pastry onto a parchment-lined baking sheet. Use a fork to prick the center area, leaving a 1-inch border.
- Spread the cooled vanilla custard evenly across the center.
- Arrange the plum slices in a concentric circle, overlapping them slightly to create a floral pattern.
- Brush the exposed pastry edges with the beaten egg wash.
- Bake at 400°F (200°C) for 25-30 minutes until the pastry edges are deep golden brown and plums are jammy.
- While the tart is hot, heat the apricot jam with lemon juice and glaze the fruit surface.
