Another important factor is how you add salt to food. I, and many other people, salt my food exclusively by picking up a pinch of salt from a bowl and putting it on/in whatever I’m making. Iodized table salt doesn’t work for that cause you can’t really get a good pinch. Different brands with their different sizes of crystal are also going to get pinched different. Typically, I use mortons kosher salt, but I’ve also used diamond kosher as well. When I used the diamond, I undersalted everything cause it’s fluffier than the mortons. I think a given volume of diamond kosher contains half the mass of iodized table salt.
