Tip

If it’s a cold day and you finish baking something, turn off the oven, open the door, and let out the warm air (not to mention the yummy smell…). Note: If you’re just baking smallish stuff, like a half batch of these delish Cranberry Hazelnut Cookies, consider a toaster oven, which use half as much energy as a conventional oven.
