I use my oven a lot to bake things and roast vegetables, usually at 350 or 400 F. It stays hot for a while afterwards, and it seems like such a waste to not somehow use that heat. Are there any dishes or kitchen maintenance things I can do with an off-but-still-hot oven?
The first thought that came to mind was to make meringues overnight.
This 'perfect meringue' recipe says to put them in an oven at 200C and then turn the oven off and leave them in until the over is cool.
There is another similar meringue cookie recipe which also states you can leave them in the oven when its off until the morning
And another for forgotten pudding which you can just 'forget' in the oven as its off.
So it would seem that this is definately an option
