I wanted to say that I used Diamond Kosher salt for my recipes. I tried Morton's Kosher salt once and it totally ruined my recipe, it was pizza. :(
It is much more concentrated than Diamond Kosher salt and will mess up the measurements in recipes that call for kosher salt.
My mother made the bagel recipe from the blog and it was too salty. It reminded me that what brand of kosher salt makes a difference in my recipes.
