4. Rotate the egg for a complete view
Slowly rotate the egg whereas holding it at an angle. This may let you look at all the contents of the egg, together with the yolk, white, air cell, and embryo (if current). Take note of any irregularities, akin to cracks or abnormalities within the yolk’s colour or consistency.
| Rotation Methodology | Description | Goal |
|—|—|—|
| Full rotation | Rotate the egg 360 levels | Supplies a whole view of the egg’s contents |
| Half rotation | Rotate the egg 180 levels | Permits for targeted examination of particular areas |
| Tilting and tilting | Slowly tilt the egg backwards and forwards | Helps decide the scale and placement of the air cell |
| Light shaking | Gently shake the egg side-to-side | Checks for unfastened or floating membranes contained in the egg |
Observing the Egg’s Inside
After getting sufficiently darkened the room and held the egg as much as the sunshine supply, you possibly can start to candle the egg. Observe the next key options of the egg’s inside:

If the big finish of the egg has an air cell of 6mm or much less, which signifies that the egg is contemporary. If the air cell is bigger than 6mm, which suggests the egg is stale.
Flashlight Take a look at
Shine a flashlight via the egg in a darkish room. Recent eggs will seem almost opaque, whereas stale eggs will enable extra mild to cross via.
Troubleshooting Candle Outcomes
Interpretation of Outcomes
Clear egg: Signifies a contemporary egg with a agency yolk and agency white.

Giant air cell: Over 1/4 inch (6 mm) excessive, signifies an older egg however nonetheless suitable for eating.
Troubleshooting Suggestions
Yolk touching the shell: Signifies a weak or damaged eggshell. Discard the egg.
