Multiple Steak Timer

One medium well steak and one well done, 2 cm thick

A well done steak needs longer than a medium well one of the same thickness, so putting them in together guarantees one of them is wrong. Start the well done one first, add the medium well one 1 min 10 later, and they finish at the same moment.

The numbers

Two temperatures, not one

Those are the temperatures on the plate. A steak keeps cooking once it leaves the pan — the centre climbs 4°C while it rests here — so the schedule takes it off the heat at about 64°C and 70°C on purpose. Probe it as it comes off and a low reading means the plan is working.

Where these times come from

Heat diffuses into meat rather than travelling at a steady rate, so cooking time goes with the square of thickness — double the thickness and you roughly quadruple the time. These times come from solving the heat equation for the centre of a 2 cm steak, not from a lookup table. Turning the steak every 30 seconds instead of once will cook it faster, by up to about 30%, and more evenly.

Cook to temperature, not to the clock

Every pan and every steak is different. The centre temperature is the only thing that is actually true, so if you own a probe thermometer use it — 68°C for medium well, 74°C for well done, measured on the plate. The useful part of a timer like this is knowing when to start each steak, and that doesn't change.
