I used to cook for a daycare and had large professional ovens. I decided to try to make a lemon desert bar and you had to bake it. It took vinegar and baking soda. I went to check on it and all I could see was yellow clouds of dough in this oven that was probably 3' x 3'. There was batter dripping off the top and when it began to subside the whole oven was a great big sticky mess!!! I apparently had used the wrong amounts!! It was like a volcano blew up in there!
