What each ingredient does

Eggs
Set firmly when heated, giving the cooked whites and yolks their solid texture.

The step that matters

Cooking for 20 minutes once boiling. Egg proteins set progressively with heat, so timing determines whether the yolk is fully firm or overcooked and chalky. Keeping the boil steady, not violent, helps the eggs cook evenly.
