Coarse Kosher Salt. 

Table salt is made by driving water into a salt deposit and evaporating the brine that is formed leaving dried cube-like crystals that look like granulated sugar. Sea salt which comes in fine or coarse crystals is made from sea water that has been trapped and evaporated. The fine crystals resemble table salt while the coarse crystals look like the grains on soft pretzels. Kosher salt is made in much the same way as table salt except that it is raked continuously during the evaporation giving it a lighter and flakier texture.
