Cooking tips
Microwave Tip : Microwave ovens use around 50 percent less energy than conventional ovens; they're most efficient for small portions or defrosting. For large meals, stovetop cooking is usually more efficient
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 : Stagger pans and baking sheets on upper and lower racks to improve airflow, and don't cover racks with foil. Food cooks more quickly and efficiently when heat circulates freely.
