3. The Crack Test (Visual Check)
Crack the egg onto a plate
Look at the yolk and white:
Yolk is round and high, white is thick and clumped → Fresh
Yolk is flat, white is watery and spreads out → Older
Pink, green, or cloudy white → Spoiled — discard immediately
Never eat eggs with off colors or foul odor.
4. The Sniff Test (Final Safety Check)
Crack the egg and smell it
Fresh egg → Neutral or slightly eggy smell
Rotten egg → Strong, sulfur-like (rotten egg) smell — toss it!
The smell comes from hydrogen sulfide — a sign of bacterial breakdown.
Cooking won’t make a rotten egg safe.
5. The Spin Test (For Hard-Boiled Eggs)
Place a hard-boiled egg on a flat surface
Spin it like a top
What happens:
Spins smoothly and fast → Freshly boiled
Wobbles or spins slowly → Older or spoiled
Works because fresh eggs have tighter, more centered yolks.
What to Do With Older (But Still Good) Eggs
Not all older eggs are bad!
Use slightly older eggs for:
Hard boiling — they peel easier than fresh ones
Baking — where texture matters less
Scrambled eggs or omelets — cook thoroughly
Just avoid using questionable eggs in dishes like poached eggs or sunny-side up, where freshness is key.
When to Toss an Egg
Discard eggs if they:
Float in water
Smell bad
Have cracked or slimy shells
Show pink, green, or iridescent discoloration
Are past the “use-by” date by more than 3–5 weeks
Eggs can last 3–5 weeks in the fridge from the day they were laid.
