You’re making a hardcore omelette , so you grab the ingredients from the fridge but notice your eggs are uncomfortably close to their use-by date. To make sure they’re good, employ this super-easy method for determining egg freshness.
What you need: Eggs and a bowl
What you do: Fill the bowl with cold water and place the eggs in the bowl. If they sink, they’re good to use. If they float, toss ’em.
Why it works: Eggshells are porous. The longer an egg has been in the fridge, the more air has passed through the shell, making it more buoyant.
