I recently started using kosher salt, but now I feel like my food is under-salted. Is kosher salt less salty?
The short answer is yes–a teaspoon of flaky kosher salt delivers less salty flavor than a teaspoon of table salt, which is more compact. Fine sea salt measures more like table salt, and has the purer, less sharp flavor many cooks prefer.
