Check the expiration or pack date on the carton
Place the egg in a bowl of water; fresh eggs sink and lie flat
If the egg stands upright in water, it is older but may still be usable
If the egg floats, discard it
Crack the egg into a separate bowl and look for a firm yolk and thick white
Check for any off smell after cracking
Inspect the shell for cracks, slime, or powdery residue
Shake the egg gently; a fresh egg should not slosh much
Candling with a bright light can help reveal the size of the air cell
Store eggs properly in the refrigerator to help maintain freshness
