Most refrigerators have a problem: they don't maintain a consistent temperature throughout their interior. No matter what temperature your fridge is set at (ideally somewhere between 37 and 40 degrees Farenheit, or 2.8 and 4.4 degrees Celsius), some areas will always be cooler than others.

  • The bottom shelf is the coolest spot
  • Keeping food items spaced out will promote air circulation (which will keep your food -- and entire fridge -- cool)
