What Temperature Should a Freezer Be?

Refrigerator temperatures come automatically set to factory recommendations, which are the proper refrigerator temperature of 37 degrees and the ideal freezer temperature of zero degrees.

These are generally the correct temperatures, but according to Whirlpool Corp., your freezer is set at the correct temperature when the ice cream is firm.

Freezer at Wrong Temperature

If the freezer is too warm or too cold, first check the air vents to make sure that nothing’s blocking circulation. Then adjust the temperature up or down one setting and allow a full 24 hours for the temperature to adjust.

One level is equal to about 1 degree of temperature, so remember: the higher the freezer temperature, the faster your frozen foods lose their quality. However, colder temperatures also could dry foods out, so try to keep the freezer at the recommended zero degrees.

Are Your Thanksgiving Leftovers Safe to Eat?

Because leftovers only remain safe to eat for four days, you’re going to want to eat up all your turkey, stuffing and gravy by Monday.

(The importance of Thanksgiving leftovers as immortalized in pop culture by the Friends Moistmaker episode)

To ensure your Thanksgiving leftovers are safe to eat, you should freeze them as soon as possible. If you throw the leftovers in freezer-safe bags or containers, they will be good to eat for another six months.

Food technically remains safe to eat forever if it’s frozen. It just loses flavor and moisture over time.

Reheating Leftovers

The USDA wrote these guidelines for safely reheating stored leftovers:

  • When reheating leftovers, be sure they reach 165° F. Use a food thermometer to check the internal temperature of the food. Reheat sauces, soups and gravies by bringing them to a rolling boil. Cover leftovers to reheat. This retains moisture and ensures that food will heat all the way through.
  • Thaw frozen leftovers safely in the refrigerator, cold water or the microwave oven. When thawing leftovers in a microwave, continue to heat it until it reaches 165 °F as measured with a food thermometer.
  • Any leftover “leftovers” thawed by the cold water method or in the microwave should be reheated to 165 °F before refreezing.
  • In a real hurry? It is safe to reheat frozen leftovers without thawing, either in a saucepan or microwave (in the case of a soup or stew) or in the oven or microwave (for example, casseroles and combination meals). Reheating will take longer than if the food is thawed first, but it is safe to do when time is short.

Make sure to occasionally stir foods when microwaving them, because foods won’t heat evenly (especially if you don’t have a turntable) and cold spots will develop in which bacteria hasn’t been properly killed.

5 Food Preservation Tips

With the opening of farmers markets and the start of many people’s CSA shares, the perennial topic of food storage becomes fresh again. Check out these 5 tips to keep your food fresh longer.

1. Use your crisper

Those clear drawers in your fridge aren’t just for convenience. Many models allow you adjust the humidity of your crisper drawers to suit their contents. Consult your use & care manual for specifics on your model, but in general, set humidity to high for green, leafy vegetables and low for fruits and vegetables with skins.

2. Pick your spot

Brands might create the perfect space for gallon-jug storage on your refrigerator door, but consider how quickly you will use highly perishable foods before storing them here. Why? Consider the temperature fluctuations of this region of the refrigerator.

If you go through a gallon of milk every couple days, then maybe it doesn’t matter. But those of use who just use a sprinkle in our coffee should definitely select a cooler spot, like the back of the fridge, which is less affected when the door opens.

Accordingly, produce like broccoli, asparagus and apples benefit from colder temperatures located near the rear. Corn and berries benefit from the warmest spot in the refrigerator, so choose those for the front.

3. Use a paper towel to keep your greens green

Greens (especially leftovers) quickly become yellows and browns.

Arrange washed greens between paper towels to absorb excess moisture and seal them in punctured plastic bags.

4. Don’t pass gas

Ethylene gas, that is. Foods like apples, peaches and pears produce ethylene, a gas that kick-starts ripening, which can cause premature aging in some fruits and damage in others. Avoid storing ethylene-producing foods near others sensitive to it, or keep them in a plastic bag to contain the gas.

5. Know what NOT to refrigerate

Sometimes the refrigerator can do more harm than good – as in the case of avocados, bananas, tomatoes, pineapples, mangoes, potatoes and squash – which should be stored at room temperature. Cold temperatures can dehydrate and damage these foods.
