Salt: Penetration, Timing, and the Dry Brine

Salt Fat Acid Heat by Samin Nosrat articulated what chefs know and home cooks frequently miss: salt is not a flavouring agent applied at the end — it is a structural ingredient that must be applied early enough to penetrate food and change its texture, flavour, and water-holding capacity from within. The dry brine technique — salting protein well in advance of cooking — is the most important single technique for producing correctly seasoned, juicy meat.

The application of salt to food in advance of cooking, allowing time for osmosis (salt draws moisture to the surface), dissolution (salt dissolves in that moisture to form a brine), and re-absorption (the brine is reabsorbed into the protein, carrying salt deep into the muscle). The result is seasoning from within, not from without.

Properly dry-brined protein tastes seasoned from within — there is no salt on the surface that can be wiped or rinsed off. The flavour is integrated. A steak salted correctly tastes of itself at full intensity; a steak salted only at serving tastes of steak with salt on top — an entirely different and lesser experience.
