two containers (at least one with a thin edge)
Step 1: Crack egg on side
Tip: do not tap too hard or the whole egg will break open.
Step 2: Turn egg over
Hold the egg over container to hold egg whites.
Step 3: Crack open egg
Gently pull the two sides open by increasing the crack.
Step 4: Catch yolk in one side of egg shell
Step 5: Pour back and forth
Step 6: Pour out egg yolk
Now you have your egg white and egg yolk seperated, repeat for and additional eggs.
Step 7: Tip: Collect missed egg yolk
If the yolk cracks open during stes 4 or 5, some yolk might gets into the egg white.
If that happens you can attempt to scoop the yolk from the egg white by using a yolk free egg shell.
The egg shell does a much better job capturing the yolk than anything else.
