Kosher Sea Salt
Sea salt is the most common type of salt used in baking. It is commonly used as a coarse dusting, a way to add flavor, and as a bleaching agent to remove iron from metal surfaces or silver from silverware.
The texture of sea salt, is that of coarse sand. When combined with a lubricant such as hot water, it is soft and does not become too heavy. Sea salt also has a somewhat sticky characteristic and may be rubbed between the fingers, but it is soft enough that you cannot actually "chop" it with your fingers.
Sea salt is very easily available and can be purchased at almost any grocery store. You will often find sea salt listed under a section for "salt", but this is a misnomer.
