Ever wonder how to test your eggs for freshness? Wonder no more! If you put your eggs in a bowl of water and they sink to the bottom, they are fresh. If they bob in the water, they are still okay, but not for long. If your eggs are floating, it's time to say goodbye!
Since it's National Egg Salad Week, I thought I'd pass on another word of advice. Hard-boiled eggs can be kept in the refrigerator in the shell for 1 week, that's it! Egg salad shouldn't be kept longer than 3-4 days.
