Why do we preheat the oven?
Almost every recipe that uses an oven recommends preheating it to a certain temperature. Is this just to help consistency and make repeatable recipes or is there some unwanted side effect of food heating up as the oven does. Uneven cooking maybe?
Just one of those things you do without questioning until you start cooking with a 12 year old.
