So you feel you're an idiot? Welcome to the club. I once made a pan of tomato sauce but it was a bit runny, so I left it on a low heat for a while. Forgot about it entirely and went out to dinner with my wife .Between the starter and the main course I remembered what I had done so I rushed off and drove home, only to find the sauce was now a layer of black cinder in the bottom of the pan. I put it in the sink, ran cold water on it and drove back to the restaurant. The waiter hadn't even noticed I had gone.
