How do you know when an egg is still fresh to use?
Fill a bowl with about 4 inches of cold water and gently place your egg inside. The freshest egg will sink to the bottom and lay on its side. Not so fresh, but still fine to eat and to cook with, if it sinks but stands on its small end. The least fresh -- unsafe to eat -- will float to the top. You also can determine a too-old egg by its sulfurous odor.
Yes the floating in water works. Sometimes you can also tell by the way it feels when u pick it up. Rotten eggs usually have an air bubble in them. It can make the egg feel wobbly when you gently shake it.
Put the uncracked egg into a bowl of water. A rotten egg will float.
The cold water test does work, floating to the bottom of a bowl of cold water, means fresh to use. If your egg floats , it is not a fresh egg.
1 fill small bowl approximately ½ full
2 add one egg
3 Fresh falls to bottom lays on side
4 Fresh enough to eat falls to bottom and stands on small end
5 Old/rotten unsafe to eat - floats
1. Check the date code on the package that it came in (if, of course, the eggs have it).
2. Water test. Add the egg (s) inside a bowl with cold water and watch the egg (s): very fresh eggs will sink to the bottom and lay on their sides. If an egg stays at the bottom but stands on its small end, it's not quite as fresh, but still fine to eat. (These "more mature" eggs will peel without sticking to the white when hard boiled and their whites are easier to whip into meringue when making desserts).
3. Crack and open an egg and check it's smell: fresh eggs tend to have little to no noticeable odor. You will notice immediately notice a pungent smell with unusable eggs.
4. After you've cracked open an egg, take a look at the inside of the shell for black or brown spots, which can indicate mold. On the contrary, dark brown or red specks (blood spots) floating in the egg white or clinging to the yolk are not an indication of spoilage and completely safe to eat or remove with a spoon.
5. Inspect the consistency of the egg white. If the egg white become watery, then the egg is not fresh, it is better not to eat such an egg.
The #5 refers to the hard-boiled egg (if it sits in your fridge).
Use the water method to test eggs: fill a bowl with cool water and add any suspect eggs. If they float, it's a sign they're no good. If they sink to the bottom and on their side = good and fresh.
