Hard boiled eggs are made by cooking eggs in boiling water without breaking the shell.
Once the egg is fully cooked and removed from the boiling water it will be solid and the yolk from the egg will no longer be runny.
As this point all you need to do is peel the shell off the egg and then eat the egg or put it with whatever dish you are making.
Boiled eggs are a popular breakfast food in many countries and it is also popular to put them in sandwiches.
