It’s not the type of salt; it’s the amount. They’ve made another change, which is to reduce the amount of salt, but tried to “cover” it by using sea salt.
This is not unlike how “new Coke” was introduced to mask the switch to high fructose corn syrup.
Yeah and they ruined Coke. It's definitely NOT the same stuff.
Same sort of thing happened to Dr. Pepper. You can only find a limited number of places that still sell what we Texans call Dublin Dr. Pepper which is made with cane sugar. Sadly, the one place here that sells it has started to water it down so that it tastes awful.
