How to Know If Eggs Are Boiled

Finding out whether your egg is boiled is very easy

As cooked and raw eggs in their shells look and feel identical, it can prove to be nearly impossible to tell them apart just by looking at them; they even feel the same weight if you hold them in your palm. If you mix them up in your refrigerator and need to discern the difference between the two, there is a simple way of finding out which have been boiled and which are still raw without having to crack any eggs unnecessarily. This can be done without using any kitchen utensils.

Instructions

1. Place the egg on the kitchen counter or a flat surface.

2. Hold the egg between your fingers and spin the egg.

3. Stop it with your finger. If it stops completely after you remove your finger then it is solid inside and therefore boiled. If it continues to spin after you remove your finger, the inside is still liquid, making it is easy for it to do so.

Tips & Warnings

• When you start spinning the egg, if it's raw it will be harder to start it moving, just as it's harder to stop it because the center is liquid.

• When boiling your eggs, avoid using eggs that have come straight from the refrigerator, as the change in temperature will cause the shells to crack.
