How do you know when eggs boil?

Tip: Just place the egg on a hard surface, like the counter, and spin it like a top. As it’s spinning, grab it with your fingers ever-so-briefly and immediately let go. If it keeps spinning, it’s raw. If it stops dead, it’s boiled.

Hard-cooked eggs should never be boiled – always simmer them in water. If you cook them for too long, the protein toughens (becomes rubbery) and a greenish or purplish ring forms around the yolk. Extremely fresh eggs are not recommended when making hard-boiled eggs, as they are very difficult to peel.
