While blueberries, raspberries, and pomegranate seeds create a vibrant and delicious topping for these pastries, you can easily customize the toppings to suit your preferences or the season. For a tropical twist, consider using diced mango or sliced kiwi, which add both color and a refreshing taste. When it comes to the custard, you can experiment with flavors by infusing the milk with citrus peels or adding a splash of almond extract along with the vanilla. If you want a richer flavor, try incorporating cocoa powder into the custard for a chocolatey variant. Moreover, you can also drizzle a fruit coulis or a caramel sauce on top of the pastries for an added layer of sweetness and flavor complexity.
