Have you ever cracked an egg only to find it smells off or looks suspicious? This common kitchen dilemma often leads to the question: do good eggs float or sink? Understanding how to test an egg’s freshness can save you from culinary mishaps and ensure your dishes turn out perfectly.
This article explores the science behind egg buoyancy, how to determine if an egg is fresh, and why it matters in your cooking. Knowing whether an egg floats or sinks can help you make better choices in the kitchen.
Do Good Eggs Float Or Sink?
Good eggs sink in water, while bad eggs float. Fresh eggs have a smaller air cell, making them denser and causing them to sink. As eggs age, the air cell enlarges, making them more buoyant and likely to float.
Understanding Egg Freshness
Egg freshness is crucial for both safety and flavor. Fresh eggs taste better and have a firmer texture. Here’s how to assess freshness:
- Check the sell-by date on the carton.
- Perform the float test.
- Inspect the egg for cracks or unusual odors.
The Float Test Explained
The float test is a simple and effective method to check an egg’s freshness. Here’s how to do it:
- Fill a bowl or glass with water.
- Gently place the egg in the water.
- Observe the egg’s behavior.
What the Results Mean
Understanding the results of the float test helps you determine the egg’s condition:
- If the egg sinks and lays flat on the bottom, it is fresh.
- If the egg stands upright on the bottom, it is still safe to eat but not as fresh.
- If the egg floats to the surface, it is no longer good and should be discarded.
Why Do Eggs Float?
Eggs float due to the air cell inside them. As eggs age, moisture and air seep through the porous shell, increasing the size of the air cell. This process decreases the egg’s density, causing it to float.
Factors Affecting Egg Freshness
- Storage conditions: Keep eggs in the refrigerator to maintain freshness.
- Packaging: Store eggs in their original carton to protect them from odors and moisture.
- Age: Eggs are best consumed within three to five weeks of the sell-by date.
How to Store Eggs Properly
- Keep eggs in the coldest part of the refrigerator, not in the door.
- Store eggs in their original carton to prevent moisture loss.
- Avoid washing eggs before storing them, as this removes the protective coating.
Signs of Spoiled Eggs
- Unpleasant odor: A rotten egg emits a sulfur-like smell.
- Discoloration: Look for unusual colors or spots on the shell.
- Unusual texture: A slimy or sticky shell indicates spoilage.
Cooking with Fresh Eggs
- Use fresh eggs for poaching, frying, or baking to achieve the best texture.
- Incorporate fresh eggs into recipes that highlight their flavor, such as custards or soufflés.
- Store leftover egg whites or yolks properly for future use.
Common Cooking Mistakes with Eggs
- Using old eggs: Always check freshness before cooking.
- Overcooking: Eggs can become rubbery if cooked too long.
- Not tempering eggs: When adding eggs to hot mixtures, temper them first to prevent curdling.
Egg Safety Guidelines
- Cook eggs until both the white and yolk are firm.
- Refrigerate leftover cooked eggs within two hours.
- Use pasteurized eggs in recipes that call for raw or undercooked eggs.
Egg Substitutes in Cooking
- Unsweetened applesauce: Use 1/4 cup for one egg in baking.

- Poaching: Crack an egg into simmering water with a splash of vinegar for a perfectly poached egg.
- Scrambling: Whisk eggs with a splash of milk and cook over low heat for creamy scrambled eggs.
Egg Nutrition Facts
- High in protein: One large egg contains about 6 grams of protein.
- Rich in vitamins: Eggs provide vitamins A, D, E, and B12.
