Ingredients

• 1 1/2 teaspoons butter
• 4 fresh peaches - peeled, pitted, and diced
• 1/4 cup maple syrup
• 1 cup all-purpose flour
• 2 tablespoons all-purpose flour
• 1/2 teaspoon salt
• 1/2 cup unsalted butter
• 2 tablespoons sour cream
• 3 egg yolks, beaten
• 1 cup white sugar
• 3 1/3 tablespoons sour cream
• 2 tablespoons all-purpose flour
• 1 pinch salt

Instructions

1. Melt 1/2 tablespoon butter in a saucepan over medium heat. Stir peaches, maple syrup, and a pinch of salt together in the melted butter; cook, stirring occasionally, until the mixture is syrupy, about 10 minutes. Remove from heat and set aside to cool.
2. Preheat oven to 425 degrees F (220 degrees C). Grease a 10x6-inch baking dish.
3. Mix 1 cup plus 2 tablespoons flour and 1/2 teaspoon salt together in a bowl. Mash unsalted butter into the flour mixture until lumps are the size of small peas. Blend 2 tablespoons sour cream into the mixture; mix until you have a dough-like mixture. Pat the dough into the bottom and up the sides of the prepared baking dish.
4. Bake in preheated oven until browned and crust-like, about 10 minutes.
5. Spread peach mixture over the crust into an even layer.
6. Beat egg yolks, sugar, 3 1/3 tablespoons sour cream, and 2 tablespoons flour together in a small bowl; pour evenly over the layer of peaches. Cover the dish with aluminum foil.
7. Bake in the preheated oven for about 35 minutes. Remove aluminum foil and continue baking until a toothpick inserted into the center comes out clean, about 10 minutes. Let cool slightly before serving warm.
