I have read that the difference between sea salt and kosher salt is that sea salt is generally processed in that it has minerals added to it which were lossed during the evaporation process while kosher does not.
Somebody also told me sea salt is inefficient for brining and it contains impurities I have also read that unprocessed sea salt and kosher salt is the same thing.

I am using saxa sea salt which on the box says is 100% natural and has no ingredients added. This being the case is it the same as kosher salt or not?


Thank you for your answer. I would like to add a related question. You said sea salt does not stick very well to meat during brining. Does this point apply to dry brining only or does it apply to brining in a water solution where the salt is dissolved?

    No, the size or shape of the crystal makes no difference once it's dissolved (it's no longer a crystal at that point). That only applies to koshering (or dry brining). The undissolved minerals are the larger problem in a brine, they'll concentrate in specific areas or just sediment at the bottom.

Kosher salt is pure, like table salt, but without any iodine and (usually) without any anti-caking agents.

Kosher salt crystals are also coarse, but flat, which makes them easy to dissolve or season/coat meat.

Unprocessed sea salt is simply coarse; the shape of the crystals (whole or ground) does not stick to meat particularly well and the impurities make it harder to dissolve properly in water. It doesn't usually have minerals added (unless it's a really cheap kind possibly made from pre-iodized table salt), it just doesn't have minerals removed like table salt.

Kosher salt and sea salt are definitely not the same thing. Kosher salt can come from seawater, like sea salt, but the "kosher" part is all about the size and shape of the crystals, not their source.

Sea salt is not a good idea for brining. It's expensive and inefficient, and by the time the meat is cooked, any distinctness of flavour will have completely disappeared. Some of the minerals may even burn, depending on the cooking method.

Instead, use kosher salt or table salt for brining and add sea salt as a seasoning afterward if you want. Using sea salt for cooking, brining, or other preparation is simply wasting it.
