Table salt is mined and highly processed to remove mineral content. It also contains the additive of Iodine. This was added in the depression era as many children were suffering a lack of this essential nutrient. As many iodine rich foods are now widely available this is no longer a problem. Table salt is basic in flavor, but can be flat or dull. I realize that many of the foods we eat come from the ground, but very few of them come from a rock.
Sea salt is produced by evaporating sea water, hence the name. It is a minimal process and Iodine is already in it naturally (in minimal amounts). When the salt is processed many minerals are left which imparts a depth of flavor unseen in table salt. As we retrieve lots of food from the sea I think of it as a much more fitting combination.
How do I buy a good sea salt?
Go to your local grocery store. Many mega-marts are now carrying a variety of good quality sea salts. Thankfully I don't have to venture to a specialty store for this basic item. I always look for a brand that sells a varying degree of coarseness. I look for a minimum of fine and coarse. This indicates to me that these people know salt. Ones with French on them are a bonus as classic sea salt comes from the French coasts.
How much should I expect to pay?
I buy La Baleine at $3 for a whopping 26.5 ounces. This seams to last forever.
Let me know what you think when you try it! Can you taste the difference?
