I am probably being stupid but my oven at home is electric and I don't know if gas is different.
We are currently on hols in a self catering caravan on a well known holiday park. This is the oven. We can't self cater as nothing is bloody cooking! We turned the oven right up but heat is just escaping. The seal doesn't go all the way round but when I called the maintenance they said firstly that it was supposed to be like that, it's only when I said my sausages had been in over an hour on gas 7 and were still anaemic that he said he would get someone to check it tomorrow. The park is full so we can't move.
