General cooking tips
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.
Oven Tips : Use glass or ceramic pans in ovens. You can turn down the temperature about 25° and foods will cook just as quickly.
Buy Local Food : See if you can find out where your food has gone before it gets to your plate. You may be suprised by the results. Often it will make financial sense for companies to transport food enourmous distances by planes, boats and lorries. This dosn't take the environmental cost into account (which of course is likely to lead to greatly increased economic costs in the long term).
