"In old farmhouses in this part of Spain, the oven used to be lit just once a week and used non-stop to make bread, roasts, rice, and cakes, and even preserves, using the latent heat as the oven cooled down. There is no single recipe for baked rice. Recipes vary depending on where in the Valencia province they come from. In some places, a beaten egg is added towards the end of the cooking process to make what is known as arroz en costra, rice with a crust."
