Lavender Cookies are so elegant and simple.
I learned a trick from another baker years ago and that is to let your oven preheat for double the time it says. The oven will be perfect for baking then. Also most cookies only need to bake 7 minutes! Yes, just 7 minutes and then take them out and let set on baking sheet for 3 or 4 more minutes before removing.
Most recipes I use just say to preheat the oven to your desired temperature, not to preheat for a specific amount of time.
I don't even preheat for casseroles and such that are more flexible in their cooking needs, so to speak. Seems like a waste of energy to me. While an empty oven is at 300 degrees, on its way up ...»
On the other hand, I understand the need to preheat for cookies and such that require a short amount of time at a specific temperature, but I don't see where preheating for longer does anything but waste energy. If that were true, wouldn't a second batch of cookies always be better than the first (which I haven't found to be true)?
