This level of precision made cooking my breakfast a fun science experiment! My results were perfect for the jammy boiled eggs i love.

Boiling an egg isn't only about the minutes in the pot. Where it starts matters: an egg straight from the fridge needs longer than one at room temperature. Where it ends matters just as much: the egg keeps cooking inside after it leaves the water, so cooling it in ice, in cold water or on the counter changes the yolk. That's why you tell us where your egg was kept and how you'll cool it, and why there's a second timer for the cooling.
