I'd been using Kosher salt for my pretzels and the flavor was ok, but they just didn't seem right.  Picked up this salt and it's really completed the recipe.  The salt sticks well has the right "salitness" and looks great. I know looks don't matter so much, but the kosher salt would kind of blend in and you couldn't even see it.  Kind of sad when the pretzel doesn't look salty.  This stuff is great!
