Even if it came from a parent, teacher, boss, or older sibling, some advice just doesn’t hold up over time. While you might have been employing the following five moves in the kitchen, you shouldn’t. Follow these tips instead.
Do not line the oven with foil
Lining the oven with foil
Use a sheet of heavy-duty foil (a few inches bigger than the cooking pan) on the rack below the one you’re using. It will catch drips and allow heat to circulate.
Don't use a pop-up thermometer for anything but a turkey
Relying on pop-up thermometers
Use a meat thermometer to check for doneness. For a turkey, insert it into the innermost part of the thigh and wing, and into the thickest part of the breast. Remember that food continues to cook for a few minutes after it has been removed from the oven.
Leaving mats in the sink
Remove the mat (and any sponges) after each use, rinse the sink thoroughly, and allow the sink to dry.
Using cooking spray on nonstick pans
Use nonstick pans on low or medium heat—without spray.
Washing certain plastics in the dishwasher
Minimize leaching by hand-washing those plastics, and consider using alternatives.
