**Make the Ashta (Custard):** In a pot over medium heat, combine heavy cream, milk, sugar, cornstarch, flour, and vanilla extract. Whisk continuously until it boils, then simmer until thickened. Cover with plastic wrap and refrigerate to cool.
**Prepare the Simple Syrup:** In another pot, boil water, sugar, and orange blossom water. Simmer for 10 minutes, then let it cool to room temperature.
**Roll the Phyllo:** Preheat the oven to 350°F. Cut the phyllo sheets to fit your pan. Lay a half sheet horizontally, place a piece of phyllo scrap vertically on one edge, and add 2 tablespoons of custard. Fold and roll tightly. Repeat until the tray is full.
**Bake:** Pour melted butter over the rolls and bake for about 20 minutes or until golden brown. While hot, drizzle with the prepared syrup.
**Serve:** Let it cool and add optional toppings like crushed pistachios and rose petals.
