So, I'm like 16, right? I come home from school one Friday in the winter and decide that we must have chocolate chip cookies. I'm too young to drive. and we don't have the logs in the fridge, and I want it to be a surprise. So I lug out a cookbook and mix all the ingredients.
And I look around and find the flour and add it. "That's funny, didn't remember the flour being in a tupperware."
Put it in to bake.
The smoke alarm goes off. The smell of burnt cookies fills the air.
Turns out I'd added confectioner's sugar, and the cookies melted when I put them in the oven and ran off the cookie sheet and burned on the bottom of the oven.
I wasn't allowed to cook again for a loooong time.
