Here are 5 reliable, easy ways to tell whether an egg is fresh or rotten — no special tools needed!
🥚 5 Ways to Tell If an Egg Is Fresh or Rotten
1. The Float Test (Most Popular)
Fill a bowl with cold water and gently place the egg in.
-
Sinks and lays flat: Very fresh
-
Sinks but stands upright: Still safe, but older
-
Floats: Rotten — throw it away
👉 Eggs float when the air pocket inside grows too large.
2. The Sniff Test
Crack the egg into a bowl.
-
Fresh: Mild or no smell
-
Bad: Strong sulfur, rotten, or sour smell
👉 If it smells bad at any point, don’t use it.
3. Check the Shell
Inspect the egg before cracking.
-
Fresh: Clean, smooth, matte shell
-
Bad signs:
-
Slimy film (bacteria)
-
Cracks
-
Powdery residue (mold)
-
4. Shake Test
Hold the egg next to your ear and gently shake.
-
Fresh: No sound
-
Old or rotten: Sloshing sound
👉 Older eggs have thinner whites and bigger air pockets.
5. Crack and Examine the Egg
Look closely after cracking it into a dish.
