Peach-Raspberry Clafouti

Butter a 12-inch round baking dish; set aside. Bring Lillet, 1 1/2 cups water, 3/4 cup sugar, and the vanilla bean and seeds to a boil in a large, wide saucepan over high heat, stirring until sugar has dissolved. Add peaches, cut side down, and cover with a round of parchment paper, placing it directly on top of peaches. Reduce heat to medium. Simmer until peaches are very tender, about 15 minutes. Remove from heat; let stand 30 minutes.

Preheat the oven to 325°F. Using a slotted spoon, transfer peaches, cut side up, to prepared dish; reserve 1/4 cup poaching liquid (discard the vanilla bean). Arrange raspberries among peaches.

Whisk eggs, remaining 1/2 cup sugar, and the salt in a medium bowl. Gradually whisk in flour. Whisk in milk, melted butter, vanilla extract, orange zest, and reserved poaching liquid. Pour around fruit.
