I bought one of these, and returned it, I had one years ago which I bought from QVC, they are now much cheaper, but, I tried baking yorkshire pudding and the pudding did rise beautifully but the bottom was raw, and I had to turn it over for the bottom to cook, I tried placing it at different levels but had no joy, did I have a faulty cooker or do they all do this, your opinions would be greatly appreciated,
