Instructions

Poach the peaches: Simmer peaches in a syrup of white wine, sugar, vanilla, honey, lemon juice, zest, and salt for about 8 minutes until skins loosen. Cool, peel, and discard pits.
Reduce the syrup by simmering until it’s about 30% of the original volume. Let it cool.
Blind-bake the puff pastry shell at 400°F (200°C) until golden and firm. Remove parchment and weights, press any puffed areas flat, and let it cool completely.
Make pastry cream: Heat milk and vanilla. Whisk together egg yolks, sugar, and cornstarch, then combine with hot milk, cooking until thickened. Remove from heat, whisk in butter, strain, and chill.
Whip diplomat cream: Beat mascarpone, heavy cream, powdered sugar, and a pinch of salt until soft peaks form. Fold in the chilled pastry cream gently until combined.
Assemble the tart: Spread diplomat cream into the cooled shell. Drizzle with reduced syrup, then arrange poached peach slices on top. Add raspberries if using.
Chill briefly (10–15 minutes) before slicing, and serve. Best enjoyed within 2 days.

Notes

Fruit swaps: Use yellow peaches, nectarines, or plums in place of white peaches.
Garnish with fresh berries for color and flavor contrast.
Shell options: Try a shortcrust or rough-puff shell if you prefer.
Syrup enhancements: Add orange blossom water or a splash of almond liqueur for extra aroma.
