Technique at a glance
A compact visual model of the lesson. Use the full mechanism and success criteria below when you practice.
Concept
Salting meat ahead of time, wet or dry, so it holds onto its own moisture under heat.
What changes
Salt dissolves in the meat's surface moisture and diffuses inward, where it does two things.
What good looks like
After twenty minutes or so the surface looks wet — that is moisture being drawn out, and it is the halfway point, not a failure.
Practice counts when you cook
Reading this brief does not change your School state. Finish a real practice dish in Cook mode and log the cook; that cook is the evidence that advances the skill.
What to focus on
Mechanism
Salt dissolves in the meat's surface moisture and diffuses inward, where it does two things. It disrupts the structure of the muscle proteins so they cannot contract as tightly when heated — and since it is that contraction that wrings water out, a salted piece of meat expels measurably less. It also lets those proteins hold more water than they otherwise would. A wet brine adds water as well as salt, which raises weight but dilutes flavour; a dry brine adds only salt, draws moisture out briefly, then reabsorbs it as concentrated seasoned liquid, and leaves the surface dry — which is what allows a crust. That is why dry brining uncovered in the refrigerator does two jobs at once. Diffusion is slow, roughly a centimetre a day, so this is a technique that rewards planning rather than intensity.
Success criteria
After twenty minutes or so the surface looks wet — that is moisture being drawn out, and it is the halfway point, not a failure.
By a few hours later the surface has gone dry and slightly tacky again, which means the liquid has been reabsorbed.
Dry-brined skin feels papery and taut rather than slippery.
The meat firms up slightly to the touch as the proteins take up salt.
Failure guards
The meat is unpleasantly salty all the way through.
Too much salt for the weight, or far too long. Wet brines are the usual culprit because the concentration keeps working the whole time it sits.
Texture is spongy, wet and faintly ham-like.
Over-brined in a wet brine. Past a point the protein structure breaks down and the meat takes on a cured texture rather than a roasted one.
No visible difference from unsalted meat.
Not enough time. Twenty minutes helps a thin cutlet; a thick roast wants overnight, and salt applied at the oven door has not gone anywhere at all.
