Is one teaspoon fleur de sel equivilant to 1 teaspoon table salt?

Answer 1

I've been looking for this answer for myself, and found the following elsewhere on the web. I haven't tested it out though, so cannot speak to its accuracy: "As a general rule: one teaspoon of regular table salt equals two teaspoons of Diamond Crystal brand kosher salt or 1-1/2 teaspoons of Morton brand kosher salt. Sea salts can generally be used interchangeably with table salt, unless they're large flakes. In that case, "Salt to taste" is the best guide."
