Why does salt draw moisture out of meat?
Short answer
Salt draws moisture out of meat by osmosis: water moves from inside the meat toward the salty surface. Given more time, the salt dissolves in that liquid and the brine is drawn back in, loosening muscle proteins so the meat holds more moisture when cooked. This is how dry-brining works.
What happens when you salt meat
- 1Salt sits on the surface
- 2Osmosis pulls water out: beads of liquid
- 3Salt dissolves into a brine
- 4Brine is reabsorbed; proteins hold more water
Step one: osmosis
Salt on the surface makes a very concentrated solution. Water inside the meat's cells moves toward it, so beads of liquid appear within minutes.
Step two: the brine goes back in
The salt dissolves in that liquid to form a brine. Over the next hour or more, salt diffuses into the meat. It changes the structure of muscle proteins so they trap more water, and the surface liquid is reabsorbed.
What this means for cooking
- Salting well ahead (an hour to overnight) seasons the meat more deeply and helps it stay juicy.
- Salting just before cooking also works, because there is no time for liquid to pool on the surface.
- Salting a short time before cooking can leave the surface wet, which makes browning harder. Pat it dry.
