If you are used to cooking with a conventional oven you will fine a number of differences to cooking with a fan oven which will require a different approach:
There are no zones of heat in a fan oven as the convection fan at the back of the oven ensures an even temperature throughout the oven.
This makes it ideal for batch baking -eg; when planning a party as all the items will be cooked within the same length of time.
Foods are cooked at a lower temperature than a conventional oven, so conventional recipe temperature may have to be reduced. Please refer to the conversion chart.
