Serious Efforts: Why preheat?
A while back, I read an article that said preheating was unnecessary and a waste of time and energy, but every recipe I've read that concerns an oven always tells me to preheat. I've actually stopped preheating when using the oven and my brownies/cookies/and even the turkey have turned out just fine. What do you guys think? Do you preheat? What are the pros and cons of preheating?
