General tips
Buy Local Food : Check out farmers markets, roadside farm stands and tailgate markets (where parking lots are temporarily transformed into areas of commerce), and don’t be afraid to ask questions about where the food is grown.
Buy Seasonal Food : Food in season is the best you can buy. Apples taste better when they haven't been flown half way around the world. And buying in season encourages local producers who, boosted by factors like the rise in farmers' markets, are building a more sustainable food industry.
Oven Tips : With conventional ovens, minimize the preheating time. Unless you're baking breads or pastries, you may not even need to preheat.
Safety in the kitchen
Don't ever leave the deep fat frying pan unattended.
Turn saucepan handles so they don't stick out (and aren't over another ring).
