The info about salt is plain wrong. Kosher salt is used for curing meat and as a mainly decorative addition to baking, you don't need to use it for cooking, it doesn't dissolve noticably slower in liquids. In fact when most recipes specify a volumetric measurement of salt they mean table salt and if you were to use kosher or sea salt you would be under seasoning due the reduced volume, nothing to do with how quickly…
