Boiled Eggs

For hard-boiled eggs, no green yolks:  

Add eggs to pan of cold water, just to cover   Bring to boil and boil 2 minutes   Remove from heat, cover and let sit for exactly 10 minutes   Immediately plunge into ice water until completely cooled   If peeling right away, move the eggs rapidly around in the pan to crack the shells. Use a teaspoon with the concave side down. Crack open a little space on the wide end of the egg and slide the spoon in to ease the shell off the egg. 

For Jammy Eggs:  

Bring water to a boil.  Take eggs from refrigerator and lower carefully into boiling water.  Boil for 6.5 minutes.  Cool immediately in ice water to stop cooking.
