How to Test the Freshness of Eggs

  1. Place the egg in a bowl of water.
  2. If the egg lays on its side at the bottom, it is still quite fresh.
  3. If the egg stands upright on the bottom, it is still fine to eat, but should be eaten very soon, or hard-boiled.
  4. If the egg floats to the top, it's past its prime, and not good for eating.

Why this method is accurate

Eggshells are very porous. Over time air passes through the shell into the egg, and its shelf life diminishes as more air enters the shell. Also, the more air that enters the shell, the more buoyant the egg becomes.

Have you ever tried this method for testing the freshness of your eggs? Does it work well for you?
