What is a defining feature of a conventional oven?

A defining feature of a conventional oven is that it typically operates without a fan, relying instead on natural convection to circulate hot air. However, when the choice indicates "has a fan," this refers specifically to a convection oven, which is a variation of a conventional oven. Convection ovens utilize a fan to circulate hot air, promoting even cooking and browning which is essential for certain dishes.

In contrast, the other methods mentioned, such as utilizing steam, using infrared technology, or operating by induction, refer to different cooking technologies that do not align with the standard functions of a conventional oven. Conventional ovens primarily use heating elements to cook food without the additional features offered by these other methods. Thus, the identification of a fan in the context of a traditional oven helps differentiate it from other cooking appliances and highlights an important aspect of modern cooking technologies.
