Table salt - the most common - is harvested from salt deposits found underground. It's highly refined and finely ground, with impurities and trace minerals removed in the process. It's also treated with an anti-caking agent to keep from clumping.
Koshering salt - or kosher salt, in the U.S. - is flakier and coarser-grained than regular table salt. Its large grain size makes it perfect for sprinkling on top of meat, where it releases a surprising blast of flavor. Kosher salt also dissolves quickly, making it a perfect all-purpose cooking salt.
Harvested from evaporated sea water, sea salt is usually unrefined and coarser-grained than table salt. It also contains some of the minerals from where it was harvested - zinc, potassium and iron among them - which give sea salt a more complex flavor profile.
