Creating New Orleans Bread Pudding can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare the Bread: In a large mixing bowl, combine the bread cubes. Set aside.
3. Make the Custard: In another bowl, whisk together the milk, granulated sugar, eggs, vanilla extract, cinnamon, nutmeg, and salt until well combined.
4. Combine Mixtures: Pour the custard mixture over the bread cubes, ensuring all pieces are soaked. Let it sit for 10 minutes to absorb.
5. Add Optional Ingredients: If desired, fold in the raisins for added sweetness and texture.
6. Transfer to Baking Dish: Pour the bread mixture into the prepared baking dish, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick comes out clean.
8. Cool: Remove from the oven and allow the pudding to cool for 10-15 minutes before serving.
9. Prepare Sauce: In a saucepan, combine the heavy cream, powdered sugar, vanilla extract, and bourbon (if using). Heat over medium heat while stirring until the sugar dissolves and the sauce thickens slightly.
10. Serve: Drizzle the sauce over the warm bread pudding before serving.
