I burned chocolate pudding. Tasted like burnt rubber. I a baked potato. One time while cooking a pork roast, the heat element in our oven caught on fire. I had to finish it on our electric grill. Best pork roast I ever made. And one time I forgot to make sure the oven was empty (my housemate has the habit of putting unfinished food in it) and caught several pizza boxes on fire, and did not notice until someone else saw the clouds of smoke. Burt cardboard smells horrible. And last but not least, I have accidentally melted several bakery cakes left in the oven for safekeeping. I always forget to check it before I turn it on....
