I love this site - so many knowledgeable people willing to share!
My latest kitchen disaster! I put some toast in my Microwave oven (its one of those that microwaves/grills and cooks convectionally too) and mistakenly selected 40 mins not 4 lol
After a while the toast was burning away merily and so I switched it off and opened a window.
Now the problem I have is that the burnt toast smell is still there in the kitchen and the microwave 10 days later.
