Bake the Pastry Rounds:
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Prepare the Pastry: Roll out the pie pastry on a lightly floured surface and cut into 4-5 inch rounds (use a cookie cutter or small bowl for uniform shapes).
- Prepare the Pastry for Baking: Place the pastry rounds on a parchment-lined baking sheet. Lightly prick the centers with a fork to prevent puffing.
- Brush with Egg Wash: Brush the edges with the beaten egg to give them a golden finish.
- Bake: Bake for 12-15 minutes, or until golden brown and crisp. Let them cool completely.
Prepare the Glazed Peaches:
- Toss the Peaches: In a bowl, toss the diced peaches with the strained apricot jam until well coated. Set aside.
Make the Sweetened Cream:
- Combine Yogurt and Sugar: In a small bowl, stir together the plain Greek yogurt (or crème fraîche) and granulated sugar until smooth.
Assemble the Tarts:
- Spread the Cream: Once the pastry rounds are cool, spread about 1 tablespoon of the sweetened cream onto each pastry round.
- Top with Peaches: Top with a generous spoonful of the glazed peaches.
- Sprinkle Pistachios: Sprinkle with chopped pistachios for a delightful crunch.
Serve:
- Serve Immediately: Serve immediately for the best texture and flavor.
