2. In a large bowl, combine the plums, 1 cup sugar, and cinnamon. Toss to coat and spread on a baking sheet.
3. Roast for 20-25 minutes, or until the plums are tender and caramelized.
4. Remove from oven and let cool slightly.
5. In a medium saucepan, bring the heavy cream, milk, and 1/2 cup sugar to a boil.

7. Gradually whisk the cornstarch mixture into the boiling cream mixture.
8. Cook over medium heat, stirring constantly, until the custard thickens and bubbles.

10. Pour the custard into a bowl and let cool completely, cover with plastic wrap pressed directly onto the surface.
11. Place the thawed puff pastry on a lightly floured surface and cut into 6-8 squares.
12. Spread a thin layer of custard onto half of each square.
13. Sprinkle with chopped pistachios.
14. Fold the remaining half of the puff pastry over the filling and seal the edges by pressing down with a fork.
15. Brush with melted butter and sprinkle with remaining sugar.
16. Bake for 20-25 minutes, or until the pastries are golden brown and the custard is bubbly.

Tips:

* For a more intense plum flavor, use ripe, sweet plums.
* If you don't have pistachios, almonds or walnuts can be substituted.
* To prevent the custard from curdling, make sure to whisk it constantly while cooking.
* Let the pastries cool slightly before serving to allow the custard to set.

Roasted plum pistachio custard pastries are a versatile delight that can be enjoyed as a snack, dessert, or even a light breakfast treat. Their combination of flavors and textures is sure to leave a lasting impression on your palate.
