Morton® Food Grade Fine is salt harvested from water taken from the Great Salt Lake using solar evaporation. The brine is concentrated in open shallow ponds and then crytallized into pure salt through slow evaporation by means of solar heat and wind. The harvested salt is washed, dried, crushed, and screened to the optimun size. Food Grade Fine tends to crytallize in pyramidal aggregates which are broken up in milling to irregular rectangular particles and are crystalline to white in appearance.
