Follow these simple steps to create your Cranberry Orange Custard Pie:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Pie Crust: If using a homemade pie crust, roll it out and fit it into a 9-inch pie dish. If using a pre-made crust, place it into the pie dish and crimp the edges.
3. Combine Cranberries and Sugar: In a medium bowl, mix the cranberries with 1/2 cup of granulated sugar, cornstarch, and salt. Toss to coat the cranberries evenly.
4. Add Orange Ingredients: Stir in the orange juice and orange zest, ensuring the cranberries are well coated. Set aside.
5. Make the Custard: In a separate bowl, whisk together the remaining 1/2 cup of sugar, eggs, heavy cream, vanilla extract, and ground cinnamon until smooth.
6. Combine Mixtures: Pour the custard mixture over the cranberry mixture in the pie crust, spreading it evenly.
7. Bake: Place the pie in the preheated oven and bake for 45-50 minutes, or until the custard is set and the cranberries are popping.
8. Cool: Remove the pie from the oven and allow it to cool on a wire rack for at least 2 hours to set completely.
9. Chill (Optional): For a refreshing dessert, refrigerate the pie for an additional hour before serving.

By following these steps, you will create a stunning and delicious Cranberry Orange Custard Pie that is sure to impress everyone.
