Why YSK: When you cook meat, any water on the surface must first evaporate before much browning can occur. You want to get as much of a Maillard reaction as possible in the limited cooking time you have before the meat reaches the correct internal temperature. Removing the moisture first means that the heat of the cooking surface isn’t wasted on evaporation and can instead interact with the meat to form the complex sugars and proteins of the Maillard reaction.

    Adding some detail. Evaporating water takes way more energy than just heating it up.
    When you put energy (heat) into water that’s below 100c it gets hotter. When you add 4,184 to a liter of water the temperature goes up by 1c. If the water is already at 100c it takes 2,260,000 to turn that into 100c steam. The energy that goes into turning water into steam isn’t going into the steak.
    So if you put a wet steak on the grill it will create an insulating layer of steam that keeps the steak at around 100c (even if the pan is above 100c).
    That’s also why you only salt your steak right before or after heating it. If you let salt sit on the steak it will draw out moisture, reducing the Maillard reaction and drying out the steak.

    For a great practical way to grill the steak perfectly, check out videos on “cold searing”.

      You can and should actually salt your steak several hours before cooking, leaving them uncovered in the fridge. Water will be drawn out, and then reabsorbed along with the salt. Dry the surface and salt again if desired right before cooking.

        Yep, salt the steak heavily the night before and leave on a wire rack in the fridge uncovered. This is called a dry brine and it’s miles better than the bland steak you get with a salty crust and watery inside if you only salt just before or after cooking.
