Convection ovens cook food by circulating hot air around the food. This method helps the food cook evenly and quickly, and it's a popular choice for many people. There are a few factors to consider when baking with a convection oven, though. First, be sure to use the correct size pan for the oven. Pans that are too large won't cook the food evenly, and pans that are too small won't cook the food effectively. Second, be sure that the food is evenly spaced in the pan. If the food isn't evenly spaced, the hot air won't circulate properly, and the food won't cook evenly. Finally, make sure that the oven is preheated before you start baking. This will ensure that the food cooks quickly and evenly.
