Steak temperatures in a water bath, and the second variable people ignore

Cooked the same cut at a range of temperatures to stop guessing. Rough guide, and then the part that matters more.

Where the temperatures land

• Around 50C: very rare, quite soft, some people find the texture unpleasantly slack.
• Around 54C: rare. Red throughout, still yielding.
• Around 57C: medium rare, and the most commonly preferred point by a distance.
• Around 60C: medium. Noticeably firmer and juices start being squeezed out.
• Above 65C: the texture changes character entirely as the collagen and proteins behave differently.

The second variable: time
Temperature sets the doneness. Time sets the texture, and that is what people miss. The same steak at the same temperature is a different thing after one hour and after six, because enzymes keep working on the connective tissue. A tender cut goes mushy if left too long; a tougher cut needs the long hold to become good at all.

Rough shape: tender cuts one to three hours, tougher cuts much longer at the same temperature.

The sear is a separate job
The bath does not brown anything. Dry the surface thoroughly, get the pan hotter than feels sensible, and sear briefly. A wet steak steams rather than browns, and this is the single most common disappointment.

Two things worth knowing

• Thickness decides the minimum time, not weight. A thick steak needs longer to reach temperature regardless of how much it weighs.
• Chilling in ice water before searing lets you sear harder without overcooking the inside, which is the trick that makes a home sear look professional.
