Make Perfect Eggs

Hard Cooked Eggs - Rubbery. Chalky, and Green Yolks?

Here’s the fix: To keep the temperature of the egg white and yolk close, heat the eggs GRADUALLY.
- Use a saucepan, cover them by an inch or two with cold water
- Set the pan over high heat
- When the water reaches a full boil, remove from heat
- Cover the pan, and let the eggs stand for 10 minutes. 

This cooks them gently and keeps the whites from toughening
