Shut the Door!

The next time you’re cooking up a mean dish of chicken tetrazzini, don’t open the oven door to see if it’s done. Each time you open the door, you allow cold(er) air to rush in, often decreasing the temperature in the oven by as much as 25 degrees. This only means that your oven will need to stay on longer to make up for the loss of heat, which will cost you more and release a little more carbon into the atmosphere. Instead of opening the door to check on your tasty treats, use that handy dandy oven light.
