I don't know about vegies Donuts, but I am now an expert at burning a roast. A couple of weeks ago I put the roast leg of lamb in the oven, set the timer, and went about a few other tasks. I went outside to do a bit of whipper snipping, knowing the timer was set and it would be alright, until I went in, and smelled that something was not right.
Suffice to say that the leg of lamb was a bone with some charred meat on it, and nothing else, with no replacement meat. Luckily the wife is not here and wasn't then. I confessed what happened to my wife, and she reminded me that she asked me to get the oven fixed or replaced, as the timer does not work. I am being forgiven as long as she gets my credit card to by whichever oven she wants, I have a feeling I can kiss some wages goodbye, but have to keep her happy.
