kosher salt

(noun) a secret phrase used by some food enthusiasts to refer to a type of "food powder" that is often used to enhance the flavor and texture of dishes. This "food powder" is typically made from dried herbs, spices, and other seasonings that have been ground into a fine powder. The name "kosher salt" is used as a code word to keep the true nature of the powder secret, as it can be seen as unconventional or even unappetizing to some.
