Food tips
Oven Tips : Check the seal on your oven door for wear. Even a small tear or gap can allow heat to wander away from your meal. A clean seal also provides better heat retention.
Oven Tips : With conventional ovens, minimize the preheating time. Unless you're baking breads or pastries, you may not even need to preheat.
Kitchen Tip : Make sure stovetop electric coils work properly. A worn-out element is a real power drain.
