The Alberger process is a method of producing salt.

It involves mechanical evaporation and uses an open evaporating pan and steam energy. This results in a three-dimensional cup-shaped flake salt, which has low bulk density, high solubility and good adhesiveness. The extremely low bulk density makes the salt highly prized in the fast-food industry due to its lower sodium content and stronger flavor for a given volume.[1][A]

Cargill operates a plant in St. Clair, Michigan that is the only plant in the United States that makes such salt.

The method was patented by Charles L. Weil on June 8, 1915.[3]
