Oven cooking

I think the most efficient way to cook food is to put everything into ceramic stoneware bowls with the lid on and place them in the oven.  Most British ovens have 3 shelves so it should be easy to have 6 ceramic cooking bowls. I like the ones with Pyrex glass lids.

Many British ovens are fan assisted, this means all 3 shelves are the same temperature because the fan pushes the air around the oven. If I set the oven to 200°c then I will know the bottom shelf will be 200°c as well as the top. If I had a large family I could cook everything in the oven, even the rice or pasta. I think you can turn off fan assistance in some ovens, that way the top shelf will be more hot then the lower shelves. Once the oven has reached the target temperature, the flame dips down small. This means I can cook 6 items on one small flame, there is nowhere for the heat to go, it slowly seeps out through the corrugated metal panels with air pockets between the sheets.
