Haven't made it through all of these, but wanted to share a couple of mine. FTR - I have been in the kitchen (with Mom or Grandmas) since I was "knee high to a grasshopper" and cooking on my own pretty much since I was 10ish. I have had my share of not enough water in the pan and overcooked something or others.
The first summer that I worked as a cook in a summer camp kitchen. We cooked about 3/4 of the food - including bread and baked goodies - by scratch.
It was the first day and we (the full kitchen staff of 6) needed to get the meal made for the staff lunch. So before the tour of the kitchen we were cooking. I had been put in charge of carrot cake. I dislike eating carrot cake, but was fine making it. I followed the directions to the T since I had not done large batch baking/cooking before. While weighing out the dry ingredients, I thought that the flour had a bit funny in texture but had been told that they used commodity flour so just thought it was a different quality than I was use to. The kitchen manager (KM) decided to wait until my cakes came out of the oven before we did the big tour. (we had the main kitchen, but also a downstairs storage area and packout room to inspect.) My cakes came out of the oven and I was horrified that they were so flat. KM said that we would check over the recipe after the tour to make sure that I had not forgotten anything like the baking powder. As we were going around the different stations of the kitchen, we stopped just before getting to the baking area to a bin under the scale that I had used for weighing the dry ingredients.
"This is the Non-Fat Dried Milk that we use to make the hot chocolate/cocoa in the mornings..." As KM went on with that explanation, my eyes got really big and I almost burst into tears. "KM? I know what I did."
Yep, I hadn't realized that the flour was over with the sugar (second bin next to it) and had thought that the NFD Milk was flour. So, basically I made a pudding cake. The camp director and most of the staff thought it was really moist. SIGH.

It was a story mentioned even in my two summers as the assistant kitchen manager.
