Time-worn household habits to break: By Consumer Reports

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

Placing aluminum foil directly on the bottom of your oven can trap heat and throw off oven performance, and might even void the manufacturer’s warranty. The foil can also melt, which can damage the oven or even cause a fire.

Instead
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

They are calibrated to pop at 180° F, past the ideal cooking temperature for turkey.

Instead
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

A rubber mat provides a cushion when you’re washing glasses and dishes, but leaving it in a stainless-steel sink can trap water underneath and cause rust and pitting. Similarly, steel wool can scratch the surface and leave steel particles, which will rust, in the sink’s surface.

Instead
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

Cooking spray can damage the coating on nonstick pans, which could cause food to stick. Very high heat can also break down the coating.

Instead
Use nonstick pans on low or medium heat—without spray.


Washing certain plastics in the dishwasher

High heat can degrade polycarbonate, a hard, translucent plastic that was commonly used in food containers, baby bottles, and sippy cups. That can cause bisphenol A, or BPA, to leach into food and drinks. Some studies have linked BPA exposure to health problems.

Instead
Minimize leaching by hand-washing those plastics, and consider using alternatives.
