Is kosher salt the same as coarse used in pickling?

No, they are not the same.

* Kosher salt is a coarse salt that has been certified as kosher by a rabbi. This means that it has been processed in a way that meets Jewish dietary laws. Kosher salt is typically used for seasoning food and preserving meat.

* Pickling salt is a type of coarse salt that is specifically used for pickling food. It is made from pure sodium chloride and does not contain any additives or preservatives. Pickling salt helps to preserve the food and prevent it from becoming mushy.

While both kosher salt and pickling salt are coarse salts, they are not the same and should not be used interchangeably. Kosher salt can be used for pickling, but pickling salt should not be used for seasoning food because it does not have any additives or preservatives.
