The Inventum IOC6070GK is a large built-in oven with basic oven functions. The oven features a 70-liter capacity and 5 rack levels. This allows you to cook several dishes, like potatoes and meat, at the same time, or cook a large oven dish for a crowd. Choose your preparation method from the different settings. Simultaneous upper and lower heat are required for most preparation methods. Upper heat only is handy if you want a crispy top layer. Lower heat only can be used for things like bain-marie cooking for traditional puddings for example.
