🔍 5 Ways to Test Egg Freshness
1. The Float Test (Best for Unbroken Eggs)
Fill a bowl with cold water
Gently place the egg in the water
Observe what happens:
✅ Sinks and lies flat → Fresh (1–6 days old)
✅ One end lifts up → A few weeks old, still good
❌ Floats to the top → Old or spoiled — discard
📌 Why it works: Older eggs have larger air cells — they float!
🚫 Don’t eat floating eggs — even if they smell okay.
2. The Shake Test (Quick & Silent)
Hold the egg close to your ear
Gently shake it
What you’ll hear:
✅ No sound → Fresh
❌ Sloshing sound → Old — moisture has separated, air cell is large
📌 Not 100% reliable, but useful for quick checks.
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:
