That is a great idea, if there is any doubt whether the egg is fresh or might be bad. There is not many things that smell as awful as an egg that has gone ad, and you just cracked it into your frying pan for breakfast .
I have only had that happen a couple times, but , believe me, I covered my nose, held my breath, and ran out of the house with the frying pan ! Much later, I went out and sprayed it out good with the hose sprayer , and then brought it back into the house and washed the skillet.
