Have you ever used Kosher salt in a recipe and found the end result to be like a salt lick and you couldn’t imagine how on earth a recipe tester could have not noticed how horribly, horribly oversalted the dish would end up? Let me guess: you were using Morton Kosher Salt. Guess what the recipe tester was probably using? Diamond Kosher Salt. And I know what you’re thinking: Now you tell me!
Believe it or not, I only learned about this disparity weeks ago but I had suspected something was wonky for a while. I use Diamond Kosher Salt so I hadn’t run into the issue but I’ve often received comments that people found even a lightly-salted dish way over the top. In short, Morton and Diamond are made differently; Morton salt presses salt granules into large flakes with rollers; Diamond, through a patented process, stacks salt pyramids to form a large crystal — one is dense, the other is like a snowflake. One is intensely salty for its volume, the other has an expected level of saltiness.
