A Salt Comparison

We’ve all been in the position of skimming a new recipe, seeing it call out a specific type of salt—whether kosher or sea salt—and defaulting to whichever we happen to have in our pantry at that time. In theory, all salt is salt, right? Well…sort of.

Variation in size and shape changes how densely salt crystals pack into a teaspoon. The denser they pack, the more salt a given unit of volume will deliver. 

So pay attention to what the recipe calls for—1/4 teaspoon of fine sea salt will have a bigger impact on your dish than the same amount of a larger-grained salt like Diamond Crystal. Using both interchangeably may mean an over- or under-seasoned meal.

When it comes to the question of kosher salt vs. sea salt, at BA, our cooking salt of choice is Diamond Crystal kosher salt: Its light and hollow flakes are easy to grip and crush, readily adhere to protein, and dissolve quickly. It’s also less salty by volume, meaning that it’s harder to oversalt. 

But there’s also a strong contingent of chefs and recipe developers who prefer fine sea salt. Ben Mims of the Los Angeles Times turns to fine sea salt to dissolve seamlessly into baked goods; cookbook author Dorie Greenspan prefers it to regular kosher salt for its cleaner taste; and Joe Yonan of The Washington Post likes its reliability: In general, brands don’t differ that drastically. 

So if you want fine sea salt to be your cooking salt of choice, go for it—but remember, when recipes call for Diamond Crystal kosher, you’ll have to adjust.

A rough conversion: About 1¼ teaspoon of coarse kosher salt will be about 1 teaspoon of fine sea salt, but be very wary—coarseness varies by brand of salt, and the only way to be absolutely sure is to take out that kitchen scale and make sure the two are equal in weight, especially in more finicky baking projects that require precision.
