Table salt, sea salt, Himalayan pink salt, kosher salt and Celtic salt are some of the different kinds of salt. These salts differ in appearance, taste, texture, mineral content and sodium content. Processors finely grind salt and add anti-caking agents to make table salt. Many table salts include iodine.
Sea salt may contain some minerals or heavy metals, depending on where salt operations harvest it. Himalayan pink salt, mined in Pakistan, gets its color from trace amounts of iron oxide, or rust. Kosher salt originated as a result of Jewish meat processing. Kosher salt is flaky and easier to pick up than table salt, but they taste about the same when dissolved in cooked foods. Celtic salt looks grey and contains less sodium than regular table salt.
