How to make eggstremely perfect boiled eggs
When boiling eggs, either soft or hard, add a large amount of salt to the water – around three-four tablespoons. This will have no effect on the flavour of the egg, but will soften the shell egg, making it much easier to peel and less likely to tear the white as you remove it.
To soft-boil an egg, cook for six minutes; to hard boil, ten.
Don't forget to plunge the eggs into iced water when cooked to prevent a grey line forming around the yolk.
