Samsung ovens with Dual Cook give you the option to prepare 2 different meals at the same time, each with a different temperature and/or cooking time. The oven uses a flexible oven space. For example, the space can be used as 1 large oven space or as 2 separate spaces when you place the separation plate in it. When you prepare 2 dishes at the same time in the Dual Cook Flex, you simply open the top half to see if this dish is ready without disturbing the preparation of the other dish.
