Sea salt is obtained directly through the evaporation of seawater. It is usually not processed, or undergoes minimal processing, and therefore retains trace levels of minerals like magnesium, potassium, calcium and other nutrients. Table salt, on the other hand, is mined from salt deposits and then processed to give it a fine texture so it’s easier to mix and use in recipes. Processing strips table salt of many of the minerals it may have contained, and additives are also usually added to prevent clumping or caking. These are the differences in the manufacturing of the two.
