There Is No More Accurate Way: The Most Accurate Way to Check the Freshness of Chicken Eggs

Have you ever opened your fridge, found a carton of eggs, and asked yourself: “Are these still good?” You’re not alone. Whether the expiration date has rubbed off or you’re just trying to avoid wasting food, knowing how to check egg freshness is a must for every home cook.

Let’s break down how it works and why it’s considered the most reliable way to check if your eggs are fresh or spoiled.
🥚 Why Egg Freshness Matters

Eating spoiled eggs isn’t just unpleasant — it can also lead to foodborne illnesses like salmonella. On the other hand, throwing away perfectly good eggs wastes food and money. So learning how to confidently test egg freshness at home is a real kitchen win.
✅ The Most Accurate Way: The Water Float Test

This old-fashioned trick has stood the test of time — because it works.
🧪 How to Do the Water Test:

    Fill a bowl or glass with cold water (deep enough to fully submerge an egg).

    Gently place the egg in the water.

    Observe what the egg does.

🔍 What the Results Mean:
⇆

    Sinks to the bottom and lays flat on its side
    → 🟢 Very fresh — perfect for frying, scrambling, or baking.

    Sinks but stands upright (on one end)
    → 🟡 Still safe, but not at peak freshness — best used in baking, hard-boiling, or recipes where texture matters less.

    Floats to the top
    → 🔴 Bad egg

    — discard it. This means air has entered the egg through the shell, and it has likely gone bad.

💡 Why This Works

Eggshells are porous, meaning air can seep in over time. The older the egg, the more air it contains — which makes it more buoyant. A fresh egg has very little air inside, so it sinks. A spoiled egg has a large air pocket, making it float.

It’s a simple application of science — and it’s more reliable than just checking the date printed on the carton.
🕵️‍♀️ Other (Less Reliable) Freshness Clues

If you want extra confirmation, here are a few other signs to check:
🥄 The Sniff Test

    Crack the egg open into a bowl.

    A fresh egg has little to no odor.

    A spoiled egg smells strongly sulfuric or rotten — unmistakable and unpleasant.

👁️ The Visual Test

    Look for unusual discoloration (pink, green, or cloudy whites can indicate bacterial growth).

    A cloudy white is actually a sign of freshness — it becomes clearer as the egg ages.

🥚 The Shake Test (Not Recommended)

Some people suggest shaking the egg and listening for sloshing, but this method is highly inaccurate. Stick to the float test.
📦 How to Store Eggs for Maximum Freshness

    Keep them in the fridge, ideally in the original carton.

    Store them on a middle or lower shelf, not in the door (the temperature fluctuates more there).

    Don’t wash eggs before storing — it removes their natural protective coating.

With proper storage, eggs can stay good for 3–5 weeks beyond the sell-by date.
🍳 Final Thoughts

So next time you’re unsure about your eggs, don’t rely on guesswork or the expiration date. Just grab a bowl of water and perform the float test — the most accurate, foolproof method out there.

It takes seconds, requires zero special tools, and can save you from tossing out good food (or eating something you shouldn’t).

Simple, science-backed, and super effective. There really is no more accurate way.
