Re: Quality built-in oven with "door open" grill
If you grill with the grill door closed, you are not grilling you are baking.
The reason to grill is to have heat from a single direction. So that you can cook the top of the food but not the rest.
Closing the door has two other problems, pans that you put it have to cook their handles. This prevents me from getting my favorite omlette pan quickly under the grill, it also makes it harder to see the moment when the top is just right. Ideally grills should be at eye level.
The need to have the door closed is driven by the need for themostats and the desire to have the control elements at the front where the heat disipates. It is certainly not to do with quality.
Professional electric grills which are only grills do not suffer from this problem. It would be possible to create a oven/microwave/grill which could grill with the door open, and be effecient in other modes but not enough customers demand it. t would cost more. Maybe grilling is going out of fashion.
