Table salt, kosher salt, and fancy sea salt are the most common types of salt we can use to enhance our food. If you want to know more about this magical rock for cooking, The Virtual Weber Bullet is your guide.
The site offers an overview of different types of edible salts, including the three mentioned above, and, more importantly, when to best use them. For barbecue cooking, for example, table salt in a rub is good for uniform distribution especially if you have other finely ground ingredients. For coarse rubs, use kosher salt: a coarse, flaky salt that is easier to pick up and sprinkle with greater control.
Just as Cooks Illustrated previously suggested, The Virtual Weber Bullet says table salt is good for everyday cooking and baking. It adds that fancy sea salt is a good "finishing salt" on cooked dishes.
A very useful chart in this article is the salt equivalent measures. If you're going to brine a turkey or other meat with salt, know that table salt and kosher salt don't have the same saltiness, so you have to measure them differently by volume to get the same effect. Use the chart to adjust accordingly.
