TO BRINE

Salting meat ahead of time, wet or dry, so it holds onto its own moisture under heat.

Why it works

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.

How to tell

• 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.

When it goes wrong

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.

The surface will not brown afterwards.

Wet-brined and not dried, or dry-brined under cover so the moisture had nowhere to go. Browning needs a dry surface.

Recovering it

Over-salted meat cannot be un-salted, but it can be diluted at the plate — serve it with something starchy and unsalted, and cut the seasoning everywhere else in the dish. A wet-brined piece that will not brown can be dried hard with paper and left uncovered in the refrigerator for an hour, which usually recovers enough surface dryness for a crust. Under-brined is the easy one: salt now, and accept that it seasons the surface rather than the interior.
