Prepare the Mixture: Start by combining the eggs, sugar, and slices of crusty bread in a bowl. Gradually incorporate the milk or, if preferred, substitute with orange juice.
Blend Smooth: Transfer the mixture to a blender. Add the cornstarch and blend for a few minutes until the texture is smooth and well-mixed.
Make the Caramel: In a pan, heat 10 tablespoons of sugar over medium heat until it melts and turns a rich golden brown.
Coat the Pan: Carefully spread the caramel evenly across the bottom of your baking pan and allow it to cool and harden.
Cook in Bain-Marie: Pour the blended mixture into the caramel-coated pan. Place the pan in a larger baking dish filled with hot water and cook in a bain-marie (water bath) for approximately 50 minutes.
Finish and Serve: Once cooked, let the dessert cool slightly before gently unmolding it. Serve warm and enjoy the delightful simplicity of this quick and easy treat!
