Ok, here it is:

It's the Celtic Sea Salt, light grey. I buy it in 5 pounds sacks and that lasts us several years. They also sell it in 1 pound bags for $5. Well worth the price! It is loaded with trace minerals that aren't found in regular refined salt.
Now another salt I use for finishing (not cooking) is Fleur de Sel.

Now all these fancy salts come in pretty big grain sizes. You want a mortar and pestle handle so you can grind them down to the texture you want.
