Questions about Hard-boiled egg
How long should you boil an egg for a firm yolk?
Lower it gently into boiling water and cook for about 10 minutes for a medium egg or 12 minutes for a large one. Cool it straight away in cold water to stop the cooking and make it easier to handle.
How do you stop the yolk of a hard-boiled egg turning green?
Avoid overcooking it: simmer for around 10–12 minutes, then cool the egg promptly in cold water. The green-grey ring is harmless; it forms when an egg is cooked for too long or cools slowly.
How do you peel a hard-boiled egg without tearing it?
Cool the egg in cold water, tap it all over to crack the shell, then peel from the wider end, where there is usually an air pocket. Peeling it under a trickle of water can help lift stubborn bits of shell.
How long do hard-boiled eggs keep in the fridge?
Keep them in their shells in a covered container and eat them within a week. Refrigerate them within two hours of cooking, and use peeled eggs within a couple of days.
What can you make with hard-boiled eggs?
Chop them into egg mayonnaise for sandwiches, halve them for a salad, or use them in Scotch eggs, where a boiled egg is wrapped in sausage meat and breadcrumbs before frying or baking. They also work well in a curried egg sandwich filling.
Can you freeze hard-boiled eggs?
Freezing whole hard-boiled eggs is not worthwhile: the whites turn tough and watery when thawed. If you need to freeze part of one, freeze the cooked yolk separately and crumble it over a dish after thawing.
Can you eat a hard-boiled egg that has been left out overnight?
No. Once cooked, eggs should be refrigerated within two hours; discard one that has been at room temperature overnight.
