a recipe calls for a hard-cooked yolks. and i don't know what that means. do you put them in boiling water? like just the yolks? or do you hard boil the egg and take out the yolk?

boil your egg for at least 10 mins. let the eggs cool and take off the shell. slice into to the eggs and you should be able to remove the hard yolk from the white good luck

boil whole eggs 10 minutes starting in cold water in a pan..AKA as hard boiled eggs

hard boil the egg and take out the yolk.
