When using glass baking dishes, decrease the temperature by 25°F (14°C). Preheat the oven before placing glass dishes in it. Use dishes suitable for the desired browning level. For a soft, light, and golden brown crust, use anodized or shiny metal pans. Dark, rough, or matte pans absorb more heat and give a darker and crispier crust. Some manufacturers recommend reducing the temperature by 25°F (14°C) when using these types of pans. Follow the manufacturer's recommendations.
