Nearly every time I cook. What can I say? I always think, "oh, it can't be THAT hot"....I'm usually wrong.
I just burned myself today and it made doing dishes very painful. I have a great husband though that is so thoughtful to offer to do the dishes for me. He also does more than his share of the cooking and kindly refers to me as his souse chef and chief pastry officer.
If you want to avoid burning your self in the oven try using those oven mitts that cover your hands completely. That way if you do bump into the top of the oven or the other oven racks it will be against the oven mitt and not your hands. Unfortunately I do not follow my own advice when it comes to putting wood on our wood stove. I just pick up a piece of wood to toss it on and then end up hitting the top of my hand on the inside edge of the stove.
I haven't burnt myself. However, when my husband was a short order cook along time ago he would come home every night with a new one. He was always burning himself. Good thing he only did that part-time and for a few months during Christmas. I can't imagine what his arms would look like now.
