How to Tell if an Egg is Bad
Knowing how to tell if an egg is bad can save you a rather severe heaving reaction or a spoiled cake mix. In general, there are 3 simple tests to try.
1- The sloshing test- Hold the ear to your egg and gently shake it from side to side. If you can hear a distinct sloshing sound then chances are that it’s bad. If no sound, it should be good.
2- Place the egg in a bowl of water. Fresh eggs will sink on their sides, a week old egg will sink but may bob slightly, whereas a bad egg will float.
3- Observation test (only do this if you’re wanting to fry or scramble the egg). Crack the egg and let it settle on a plate. If the yolk sits high upon a gathered white then it’s fresh. If it sits slightly lower then it’s probably a couple of weeks old, but if the yolk lies flat and the white is very runny then it is bad.
If using several eggs at once, be sure to test them individually before adding them into your mixing dish, as otherwise you will ruin the whole batter.
