I was posed a great question tonight at my 80/20 Lifestyle Class. What is the difference between sea salt and Kosher salt. Well, after a little research I found some answers. Below is the most relevant, but I am also attaching the link if you would like to learn more about different salt types.

Sea salt is harvested from evaporated seawater and receives little or no processing, leaving intact the minerals from the water it came from. These minerals flavor and color the salt slightly. However, because these salts are usually expensive, it is worth keeping in mind that they lose their unique flavor when cooked or dissolved.
Kosher salt takes its name from its use in the koshering process. It contains no preservatives and can be derived from either seawater or underground sources. Aside from being a great salt to keep within arm's reach when you are cooking, it is particularly useful in preserving, because its large crystals draw moisture out of meats and other foods more effectively than other salts.
