A student shared a cooking experience. She was making regular-sized muffins. After filling the regular-sized muffin tins, she placed the muffins in the oven and checked the recipe to see the cook time. It said that if you were making mini muffins, reduce the cook time by 10 minutes. If you are making jumbo muffins, to turn up the heat and cook the muffins longer. She thought, "Gee, I'd like jumbo muffins!" so she turned up the heat and incinerated her regular-sized muffins.
